New Vintage Alfred Sung Silk Shorts

My mother purchased these for me in the 80’s at an Alfred Sung sample sale. Beautiful silk but I was too young to be keen on such fancy pants. Never been worn. Elastic waist. Side slit pockets. Size small as they measure: 20” in length, with about a 12” rise, and 20” at its widest point below hip bone. I’ve modelled them in last photo but note they are a tad too small on me. I am a 6 so they are definitely a size 4. I will post as size small.
