Great Tank Top
Color: White, Size: Large
I love this top. It fits snug and is comfortable. The length is perfect. I especially like the wide shoulder straps which hides my bra straps. I’ll order more of these in different colors.

Get it!!
Color: White, Size: Small
Great tank and definitely want to buy in more colors! Thick enough to not be see through but not to make you die of a heat stroke. Good cut and cute fit! Seems like it’ll last awhile! Perfect as a top or as an under layer if needed.
