Can anyone help me find a t-shirt type bra that will suit narrow shoulders ?. I’m a 34E and have finally decided I’ve had enough of bra straps slipping off my shoulders every 5 minutes. Racer or Cross back would be great, but sports bras don’t work as they are too tight for all day use and dig into my ribcage after a few hours. The straps on a standard bra are just too far apart to stay in place. Thank you !
