Yoga pants are slightly better than those god-awful capri-legging and ankle-elastic ones people are bafflingly bringing back into vogue... Not being one to worship runway fashion, I think there's been quite enough eighties revival already, and I could do without them deifying the weird kid in third grade, who wouldn't wear a coat and whose tube socks were always showing beneath the too-short elastic ankles of his sweatpants while he ate strawberry-flavored air for lunch.
Even if they are showing on the runways and in magazines, do reconsider sweatpants and stretch pants-- they can make almost any girl look fat, and certainly every girl look worse than they could in a structured dark jean or a pinstriped trouser. If pants with a waistband that doesn't give are your big issue because you just had a kid or you've gained a bit, for the love of all that's holy, get your mind off the number and buy a flattering pair that fits even if you have to go up a few sizes and/or have something tailored so it fits your biggest bits but nips in around your small ones. Forget the size. Examine how it makes your body look. Find someone to be objective if you cannot be. You will feel so much better about yourself if you see how beautiful you can be with three seconds more effort (like a button); and a non-stretchy waistband is helpful for reminding you when to stop stuffing handfuls of kettle corn down your gullet (for example).
These girls will never, ever have more bangin' bodies than they do now, in college. And they're wasting it all!
Some of you will dislike my vehemence on this subject, as I banish your favorite comfortable clothes to the same hell reserved for Crocs,Uggs, and Leggings Used as Pants without a Tunic (very similar to the sweatpant situation but even worse because everyone sees EVERYTHING, girl.) Sorry about that. But don't you want your booty to look the best it can?
