The hardest thing for me in thrifting is to STOP having a 'found!' jolt when I find things that used to sell well but which no longer do. There was a time I'd pick up Chicos Travelers items in any color, any size, and they'd sell like hotcakes. Now? Pfft. With the exception of the largest size, the brightest prints, and mid-summer, I can't even give them away. But I still get that little shock when I find them. And then I pass them by.
Perhaps stylish men's clothing have less of that sort of thing (or men have always been smarter than to wear slinky acetate fabrics).
Yes. Also terrible when you get that "found!" jolt on something super awesome only to find it has a size 11 doo doo footprint on the back of it and you have to dejectedly return it to the rack for the next poor bastard to get excited about.
