See By Chloe Silk Viscose Pleated blouse top size 4

Such a pretty See by Chloe top I purchased from a vintage shop. Off white color, balloon sleeves with lovely pleating details. Size is US 4 or Small but it’s a flowy fit. Material is silk viscose blend. Caveat here is that there is slight discoloration at the seam of each underarm and I haven’t been able to get it out. (See last 2 pics) It’s not very noticeable, especially when the top is on because the sleeves are so billowy- but it’s there. I have cleaned the top a few times but admittedly I’m not patient or a cleaning wiz (I use natural products only) so maybe you want to take a chance? lol. Otherwise the top is in excellent condition and so cute.
