Anyone ever purchase workout clothes from popflex active?

So I just ordered a few items from Cassie Ho's fitness apparel line, Popflex Active. This is my first time buying and I'm a bit skeptical about it because I don't know what to expect. I hate ordering clothes online! Some of the reviews I've read say they are good quality but run small compared to the measurements on their size chart. I ordered a size 6 in everything but I'm afraid I should have sized up to an 8. I was just wondering if anyone has tried it and can tell me what they think of it. Thank you!
