I just started doing yoga this summer and I came here to buy some sweat-appropriate wear :] it's true that lululemon is pretty overpriced but (insert something about special luon cloth or something).
The girl who helped me out was so helpful and fun! Lululemon, as every girl's dream, has everything in a million colours and we talked about colours and sizes. (Oh yeah. Size up here. I found everything ran a little small for some reason.) I was also pretty nervous about starting yoga since my first class was going to be a hot yoga class, but she helped calm me down, psych me up, and find all the perfect things to wear to class!
(When I went to class, all the clothing and everything held up perfectly and worked really well.)
