Color: Black. White is also available separately. No noticeable stains. Size: S It's a loose fit, so even S is a bit oversized. I wore it a few times at home while breastfeeding. After that, it was stored at home. I've never worn it outside. Trendy back-henley design. Made of soft, comfortable material. It's a 2-way design that can be worn both front and back, allowing for various styling options.
