Wedding Dress Care/Content Labeling follow-up

I admit that sometimes I make mistakes. A person reading my previous blog entry on a wedding care/content label pointed out some inaccuracies in how I wrote my suggested label. The FTC has some guidelines on how to write labels, both for content and care. I've read these instructions many times, but I sometimes need a refresher. Yes, it would be a good idea for anyone who has to write labels to read the instructions themselves rather than rely on a blog entry (or an anonymous commenter).*

Care instructions follow the general form:

Washing
Bleaching
Drying
Ironing
Warnings

If a dress truly cannot be dry cleaned, then the label should include that instruction. My label suggestion would be more accurate if I had included that instruction. I had also placed the bleaching instruction in the wrong order. Perhaps a better, more accurate, and perhaps correct label (changes in bold) would read:

100% Polyester
Do not dry clean.
Hand wash or
Spot clean in cold
water with mild
soap. Do not bleach.
Hang to dry.
Do not iron.
Made in China
RN12345 (<------ Made up)
---------------------
Avoid the use of
alcohol based products
such as hairspray,
perfume, etc., as these
may damage the dress.

The commenter also pointed out that if there is a reasonable basis for care instructions, then a manufacturer does not need to destroy a dress to prove it. I guess the question that must be determined is what is reasonable? In my opinion (and just for this commenter, this IS my opinion, for what it's worth), a new wedding dress manufacturer should destroy a few dresses to prove their labels. If you think something can be dry cleaned, you should be able to prove it. Same with any other care instructions. Over time, you may be able to reduce the type and amount of testing provided you do not change your component parts. This is probably the reason behind some of the testing requirements in the CPSIA. When you change a component (sometimes even from the same source), you have introduced a variable which may result in different testing guidelines.

I know wedding dresses are expensive, even the initial samples. Is it reasonable that every dress be tested to prove the care instructions? I am not sure every manufacturer goes to that extreme. But it is reasonable that a few have been. Testing a whole complete unit is the only way to test for compatibility of components. Testing a whole complete unit will tell you what a customer will experience. Wedding dresses have a lot of sentimental value and you wouldn't want a customer to have a dress ruined by poor or incorrect cleaning instructions. But this decision is best left to the manufacturer and the responsibility they are willing to bear if something were to go wrong.

As a manufacturer develops, it is reasonable to also test components. It is common for a manufacturer to use the same polyester satin in multiple styles and all they do is change up the trimming. In this case, the satin has probably been washed tested a few times and they know how it should be cleaned. But the trimming is different. In this case, I take some yardage, stitch the trim on and wash it (or dry clean it) - multiple times.

I can recall some concern I had about some flocked glitter on a chiffon. The glitter can fall off because the dry cleaning solvents will dissolve the glue. Washing by hand or machine can cause the glitter to fall off due to abrasion. So we tested various scenarios and came up with a reasonable basis for care. The same scenario can be applied to beads. Though I must say, based on my experience testing, some beads can be dry cleaned and some cannot. Some will fall apart even when hand washing. You won't know unless you test.

It is reasonable that a manufacturer has proof for the testing they recommend. I believe this includes documentation. You won't have documentation unless you test something. These days, I am not sure that a government regulator will appreciate your good intentions or your word without some kind of proof.

And finally, it is true that the CPSIA does not specifically mention wash testing (as I stated in my previous blog entry). It does imply that any testing be done by a certified 3rd party lab. When I worked various private label programs for Big Box stores, they required wash testing by an approved 3rd party testing lab. At that time we were able to negotiate creating an in-house wash testing program to save money. We were required to submit a copy of our test results with the 3rd party testing reports to the technical designers of the big box stores. In the days of CPSIA, I imagine this is no longer possible (I haven't worked on any private label programs in a while, so someone else who has will have to clarify this point). So while the law may not specifically mention wash testing by a certified lab, Big Box retailers might require it anyway. This is thus my reasoning for why I said what I said.

*When I wrote my original blog entry, the FTC site was down and had been down for a few weeks. My intention was to verify and correct my article and I didn't do that because I couldn't. It was one of those things that fell off my radar and I didn't get back to it. My apologies to anyone if I misled. I appreciate comments that politely correct me when I have misstated something. However, I won't print comments that are insulting and offensive.

Wedding Dress Care-Content Labeling

Care content label in a wedding dress

This article now has a follow-up blog entry with some corrections and additional opinions. Your comments are welcome, but hateful or spammy comments will be deleted.

As I was working on the alterations for this wedding dress, I wanted to see other dresses by this designer/maker. Perhaps the sleeve pattern shaping was intentional and not a mistake? Perhaps the problem is consistently found in other styles? I had no idea who the designer was, only where the dress was purchased. The dress was not in the store's web catalog and the only label in the dress was not helpful. The dress was missing a brand label and had no RN number. Further, the care instructions were rather bizarre/interesting (click on the picture for a closer view). I googled the style number and came up empty.

At a minimum, the dress should have had an RN number on the label. You can search an FTC database to find out the manufacturer of an apparel item. Wedding dress manufacturers/bridal shops have been fined in the past for failing to disclose or intentionally removing this information. Alterationists may remove the labels after purchase but should give them to the bride (links to come later as the FTC website was having problems when I wrote this).

The label states:

100% polyester
Do not dryclean
Spot clean ONLY
Use cold water and
mild soap
Made in China
See reverse for care
----------------------
Do not spray Alcohol
based product directly
on gown such as Perfume,
Hairspray....etc. This will
damage beadworks and
embroiderie designs made of
Rayon, Nylon, and other
synthetic materials.

I found the care instructions rather hilarious. How many of you spot cleaned your wedding dress with only cold water and mild soap? The fabrics themselves probably could be dry cleaned or even hand washed (though that may be more work). The beads will probably dissolve in the dry cleaning solvents, so thus the "do not dry clean" instructions. But, if you can find a reputable dry cleaner who will clean the dress and avoid the beads, then go ahead and have the dress dry cleaned. Otherwise, hand wash the dress. BTW, there were no further care instructions on the back of the label. Many wedding dresses are currently manufactured in China, which may explain the poorly written tag.

The extra instructions are interesting. I suppose it is possible that perfume or hairspray may damage the beads. Though the bride would probably need to be drenched in it before the beads dissolved. Sure would like to put those beads to the test....

The label should have been written to say:

100% Polyester
Hand wash or
Spot clean
in cold water with
mild soap. Hang to
dry. Do not bleach,
Do not iron.
Made in China
RN12345 ( ------ Made up)
---------------------
Avoid the use of
Alcohol based products
such as hairspray,
perfume, etc., as these
may damage the dress.

And of course, the care instructions should be thoroughly tested by the manufacturer. Good industry practice (and the government) dictate that a manufacturer should have a reasonable basis for the cleaning instructions. This means actual test data recorded and stored with the manufacturer. At this point in time, manufacturers (except children's clothing manufacturers) can do their own in-house wash testing. Children's clothing manufacturers will have to have it done by a certified laboratory. Wash testing is not specifically mentioned in the CPSIA, but it does imply that ANY testing will have to be done in a certified lab.

Accounting for shrinkage and/or stretch in sewing patterns

Leggings and pants

Just a few comments I made in the Fashion Incubator forum when making patterns to accommodate stretch (knits, stretch wovens) and/or shrinkage.

Have to be careful when scaling patterns in CAD. Shrinkage/stretch is not proportionally the same in both directions. Many pattern making books advise to add the same amount of change to the length as the width. Don't do this. The only way to know is to know the fabric. Things shrink more in length than width. I am so sick of washing pants and long sleeve shirts and having them end up too short. If anything, remove width ease and add length on knits. It sounds counter-intuitive but prevents high-waters. Not sure on stretch denims, so test, test, test.
In my Etsy shop I have a simple tech pack kit that includes a wash testing form. The wash testing form includes instructions and formulas to figure out shrinkage in both the length and width of a fabric. It is well worth the investment of time and money to test your fabrics for shrinkage, particularly knit fabrics. Once you know the approximate shrinkage of a knit fabric, I recommend adding the extra width and length needed to accommodate expected shrinkage.

Adding a shrinkage allowance to a pattern piece may cause the finished garment to look proportionally wrong. If you do not pre-wash the finished item before shipping to the retailer, the item may look wrong on the hanger and the customer may decline purchasing the item because it does not appear to fit. So there is a limit to the amount of shrinkage you can include in a pattern before proportions, fit, and hanger appeal are impacted. Generally, you can include about 3-5% shrinkage in a pattern without too much of an impact. If your wash testing results return a shrinkage greater than 5%, then you either need to reject the fabric or pre-shrink the fabric before cutting and sewing.

Knits in particular add an added layer to product development because they are more likely to shrink. There are various types of knit fabrics with different types of finishing. Some knits are pre-shrunk at the factory and some are not depending on whether the fabric will be printed or dyed at a later date. When sourcing knits it is important to ask about shrinkage.

Accounting for stretch in knit fabrics is also another added layer. Stretch influences fit. Should the item fit close to the body? If so, the pattern needs to be reduced in width and length. This is another area where the amount to reduce will be different for the length and width. As an item is stretched in one direction, the other direction also changes. You may notice this when you stretch a knit t-shirt in the width direction - the length of the t-shirt will shorten. This is a complex topic and the answers depend entirely on the style and chosen fabric.
