I sleep in the Tank. Straps never did in and there is enough room for “the girls” in this style (I am a double D). I have several colors! Oh and these are super soft and comfy! Will keep using and buying these!
The tank was the last style of bras I tried— I just worried it would flatten my already small 34B cups and make my chest nonexistent. Happily not! In addition to being soft and comfy (Knickey’s signature) they are also very flattering! This style is the easiest to wear for a variety of things, including sleep and low activity. I’ll be buying more!
