That lady is an idiot.
No crop top for working out.
No yoga pants out and about.
I'm a skinny person and I still don't feel comfortable wearing a crop top and my stomach showing. I'm not really a modest person, I do like to show a bit of skin but it's definitely not going to be when working out or wearing yoga pants to the mall. Crop tops aren't all they're made out to be either, when I wear one I'm constantly pulling it up so my girls don't fall out or it squishes them and just doesn't look very flattering...
That girl in the picture with the crop top needs some groceries.. she has absolutely no bottom. I'd rather be curvy than look like a stick.
I do stick by a good bit of fashion rules though, NO brown and black together..Ever.. no white pants, I don't want to see your underwear or bra.. the list goes on.
