I really love the concept behind this bra. And I truly appreciate that it is so versatile in size. It *almost fits me. I am slender person by nature, but since having a baby my breasts grew FIVE cup sizes :( so having a small rib cage and very large breasts, I have looked high and low for a good sports bra. My Shefit bra is as tight as it can go, with just a little spillage out of the top. I believe the next size up would be too large around. When I get it all situated, it has some pretty decent support. Some suggestions that I have: 1. Possibly an adjustment in sizing. I am wearing the 1 luxe and it’s not quite tight enough around, but the cups are just a tiny bit too small. And 2. I would love to see a change in the material. I use to wear Lululemon bras when they would fit. And since the pricing is comparable I would love to see the comfort/quality comparable as well. It was rubbing around the rib cage, and uncomfortable on my nipples. I definitely will continue to wear and love this bra, and look forward to the 2.0!!
