Color not as pictured
Color: Purple, Size: Small
Love the top but the color is not even close to what is pictured. Ordered purple, the package label says it's purple, but it is bright hot pink.

Comfortable and gives a lovely sillhouette
Size: 36F, Color: Taupe Tan
This is one of my favorite bras, even over my usual expensive Third Love bras. It somehow magically supports your bust without constricting it, so you look like you're not even wearing a bra and just have naturally perky breasts. I find I can wear it all day long without discomfort. I've owned for over 3 months, wearing and washing weekly, and it still looks brand new and hasn't lost any elasticity. I'm typically a 34F to 36E depending on brand (I wear 34F in 3rd Love Smoothing Full Coverage, and a 34F in their Comfort Stretch Front Close and 24/7 Classic Wireless), and I ordered this in the 36F. It fits perfectly like a second skin and shows minimal indentions in the back where the bra lies, but no lines anywhere else (I carry my weight in my core and always have lumps and bumps with bras, this one is way better than most). Back to buy more.

My FAVORITE Bra!
Size: 44F, Color: Black
These are my FAVORITE bras!! They hold everything in and there is no spillage out of the cups! I own many of these and have yet to be disappointed. I like that they don't cost and arm and a leg either!
