Cut tight, good quality and price.
Color: Sky Blue, Size: Medium
Well made, the material is soft, and comfortable. It’s tight without being clingy. It didn’t shrink when I dried it on medium. The color is as shown and its not see through but is cut tight. So if you have a little extra weight in your stomach area it will not be flattering. Great price and good quality. I’m 5’6, 138lbs, and wear a 36C. I bought a size medium.

Comfortable women’s top, excellent for nursing!
Color: Black, Size: Large
I needed a new breastfeeding friendly tank top as I am postpartum and gained some weight. This is so comfortable and easily accessible for feeds. I wear it around the house and to sleep in. At a fraction of the cost of the more expensive brands nursing tops, this is a great practical, comfortable buy. The material is thick but breathable and not restrictive and non see through. Sizing is spot on. I am 5’4 and 160 lbs and I bought a Large. Overall this is a durable piece that is a staple in my postpartum wardrobe.

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.

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.
