Great year round tank top. I have quite a few of them, I just don't wear this color often. Fits true to form as a medium, with a boxy style. Back is just a tad longer than the front. Button closure on top back. Tank is in great shape, barely worn, meticulously loved and cared for. Non smoking pet free home, ships next day! From Quince Listing; You wouldn't usually think of a tank top as a year-round piece, right? Think again. Our linen tank is great to layer up when it's chillier, but stands alone on warmer days. Our linen is made from 100% European flax, which is more sustainable and less resource-intensive to grow. Linen is the ultimate temperature-proof fabric because it's breathable and naturally heat-regulating. Ethically woven from 100% European flax linen Breathable, durable, hypoallergenic, lightweight Button keyhole opening at back neck This material is certified by OEKO-TEX Standard 100 (Certificate Number: BJ050 139683) which ensures that no hazardous substances are present
