Cream blue full length prom formal dress size 2

This is a long prom dress with cream/off-white bodice and blue skirt, it's a heavy fabric almost like satin. It's a beautiful dress but I really can't fit into it anymore! Only worn on prom night. There's a slit up the leg, it doesn't hit to the bodice, it stops at mid thigh. It's a size 2 and would fit a 0-2 best. I'll try and take more pictures, but I really can't put it on anymore.
