I'm not the brand whore type, but if I was, I'd definitely shop here.
I simply cannot bring myself to spend the equivalency of a plane ticket on a yoga outfit, but I hear time and time again that it's worth every penny, so I'll chip in with a gift card here and there to help ease the cost for friends that swear by it instead.
I try and spread the Lulu love where I can simply because I love what they do, particularly in terms of offering free yoga. I've attended their outdoor Sunday yoga sessions (10 am) on more than one occasion and have loved it every time. Most of the others do it too, and I think it's such a super cool way to give back to the community. I encourage all to give it a try!
