I was interested in trying some, as some FB friends are really into them and they looked cute on them. One day while shopping at HEB, I bought a pair of their under $10 leggings (over by the hair bows) and I wear them with a long top as PJ's. Comfy enough for me. I did wear a pair of leggings I got for $10 from Zulily (Christmas ones) with a long black tunic and knee high boots out in public when I was in Arizona. That was the first time I actually wore leggings in public and I wasn't scared about it. ONLY with a long top and boots though. I personally wouldn't spend $30 or more on a pair of leggings, and I think there are some specific washing/drying instructions....no thanks...too much high maintenance for a pair of leggings.
I agree with Littlegoo, it has to be with a longer top or dress and boots!!! ANYTHING ELSE if you're over 10 years old is uncalled for. I'm seriously thinking about having a rep at my house for a "party" so my friends (and ME) can try them on first. I've heard they are the best. They only make so many of one print and then it's retired.
