One comment from a reader on my Designers hate care/content labeling blog made a good point. Labels can be very irritating to the end user. Rest assured, it is perfectly legal to remove labels after purchase. The size and placement of labels should concern designers because it is all related to your brand. I searched through my stash to find examples of how other designers deal with US labeling requirements. I could not find any pieces that did not comply with labeling requirements. I guess I tend to buy product that is honest in their labeling. Clothing that leaves off labels or fail to place them properly says something about your company (and it isn't good IMO). All of these examples have the labels correctly placed near the back neck with the country of origin prominently displayed.
Country of origin as part of the brand label. This is also one of my rare Made in USA pieces.
A size tag/country of origin label stitched to the bottom of the brand label.
A separate size/country of origin label placed next to the brand label.
This is a typical example. The brand label is stacked on top of the care/content tag. The country of origin clearly shows below the brand tag.
