Our super soft super comfy sleep bra. Great for wearing indoors (ie when you're rocking around the house or going to bed). Light support. No underwires or wires of any kind. 92% Nylon 8% Spandex fabrication. Cool wash cool dry. Hang dry for longer life. The straps narrowest point at the shoulders are 1.25-1.5 inches (depending on size). The bras are super stretchy - if you're looking for something super supportive (ie - they pull you in really tight) these probably aren't going to work for you. These are the type of nursing bras you want if you want something soft/stretchy and need room to grow. We've attempted to try these on - on different ladies in the office and here are the best sizes we've been able to coordinate to (below). If you have other size suggestions please add them below.
