Many of my dress shirts are showing wear on the edges of the cuffs. The shirts are all 3-4 years old, non-French cuff, and are made by Thomas Pink and YSL. I know Pink has a bad reputation around here, but it's not total garbage. I'm wondering what causes this type of wear around the cuff edges. Is it normal for shirts this age to wear out? Is it because the place I have them laundered and pressed is doing a lousy job? Could it be because the sleeves are a little bit too long on many of the shirts? Something else? Any insight appreciated. Thanks.
