Honestly I am pretty fussy about my own clothes, but I don't really care that mug what others are wearing.
The thing I really hate tho is that clothes do no seem to come in my size, and I know people of various sizes also have this problem. I am about the size of an 11-12 years old girl. I hate that I should have to buy children's clothing at 33 years old. I know this is just as frustrating at the other end of the spectrum.
*I like maxi dresses too, they are really nice. Unfortunately on me I look like a one of Snow White's dwarves dressed in Snow Whites clothing.
