The stripes pattern is a little different from lululemon's Parallel Stripe print but if you're looking for a spare pair to save wear and tear on your valuable PS WUCs these are a nice substitute.
Lululemon has made a very similar (identical?) stripe before - this a SeaWheeze-edition Bound Bra next to the Chaturangas.
I also bought this Essence tank while I was at the store. I know it's a polyester blend but it's super soft, looks very cute from the back, and, most importantly, has "unstinkable" technology. I like my lululemon cotton tanks a lot but I didn't like the one time I wore my pima Trapeze Twist for a vigorous workout and it really took up and retained odor. The price is also a very attractive $39.
