I am 5'9", size 12/14 bottom and 14/16 top. I am very, very short waisted. What i want to wear are my nice shirts and blouses loosely tucked into a waistline but i know this makes me look like a barrage balloon. When i leave the shirts untucked they billow out from my heaving chest and increase my size. is there anything i can do to avoid binning them.
