Chicos blazer / jacket in cream / winter white

This is a Chicos blazer in a nice cream color. It's quite heavy for a blazer and should be comfortable during the summer months. I don't profess to know anything about Chicos proprietary sizing system, but it is a Chicos size one. It fits about what I would guess to be a generous ten in regular sizing. It's also stretchy. There are some marks under the lapel that I didn't notice until today. I will try to get to get them out at the dry cleaner, but they don't show anyway. ( See lapel photo)
