NWOT John Paul Richard Baby Blue 100% Silk Blazer

This blazer came out of my grandmothers collection (more to come on that!!) Apparently light blue silk is very rare! This jacket is in NWOT condition! Measurements: Length: 25” Bust: 36” Sleeve 20” There is a small mark from what looks like a blue pen… I haven’t tried to clean it (bc I’m not familiar with cleaning silk) make me an offer!
