Pretty solid for the price. I got a very interesting pair of leggings that I wouldn't normally buy but I'm not upset about it. The top is sooooo nice and soft. My total outfit retails for $165 ($66 top, $99 bottom). I'm very tempted to get another set to test out my luck.
I've bought the mystery pack twice. First time, I got blsck cropped leggings and a gray sports bra. Both were still full retail either on BY or other mass retailers. Neither was "my style" but both became my favorite pieces. My second order included full-length black leggings and a gray hoodie. Again, not "my style" but now I live in the hoodie and wear leggings pretty much right after each wash. All the pieces wash well on cold cycle and air dry. No pilling yet.
