Peach Lace Halter Chiffon Dress Gown Size 12 Gown w Shawl

Peach Lace Gown size 12 with Shawl I never fit this, yet feel it's too pretty to give away. Comes with a matching lace shawl which may be hard to see in the pic. Tempted to tailor it to fit me, but afraid I'll make it worse by lowering it's value and making it not being able to fit anybody or even fix. Shawl is 19 1/1" wide and 74" long
