True to size & color, modest cut, fitted style
Color: Purple, Size: Small
The cut on these tops are perfect. It's a nice v-neck without being revealing. Thick straps and solid back so your bra doesn't show. Sizing is accurate in my case. 5'6" 130lbs chest 34" waist 26" hips 39" and I ordered the small which is fitted on me. I ordered the lavender purple and a black one and both colors are correct in shade. Soft and stretchy material. I air dry them mostly and only gentle low on the dryer if needed and have not had any shrinking.

Great top for summer!
Color: Navy Blue, Size: Large
I bought one of these. The v-neck and fit of the tank top is amazing! Flattering! I loved it so much I ordered two more. Great summer tank! Washes and dries fabulously as well. I am 5’4” 150lbs, wear a medium or size 8-10. I purchased a large and love the look. It fits well, not too tight but hugs the body. Not oversized.

Comfortable Fit without over compression
Size: 38B, Color: Gentle Rose
This is a good post surgical bra. I had a lumpectomy and it gave me enough support without being too tight. It is adjustable in the front and the shoulders. Use the size chart to get your best fit. Soft material. Comfortable enough I wore it 24/7 for a couple days. Only downside is handwashing but I will try the delicate cycle on my machine and air dry always.

Awesome bra!
This bra is so comfortable. I love the fact that you can adjust the straps and the front to make it fit a short person's torso. This bra lifts and so far, has not stretched out.
