I saw this really cool idea - the t short extender, or topless undershirt by Blush. They recommend it for both pregnant ladies and people who just want to avoid flashing their muffin top.
I am always looking for shirts that are long enough to cover up the midriff and I would love one of these.
I saw them on the this site that selles stylish maternity clothes but they are not in larger sizez... Sounds like a money making opportunity for someone.
