Beautiful long sleeve silk blouse from J.Crew in a beautiful cobalt/Royal Blue. 100% silk. I always dry cleaned this top — I’ve only worn a handful of times - but I don’t think they paid attention to the (pits) when cleaning so there’s slight (salt) water marks. Looks like google is suggesting a diluted vinegar solution to get it out. Buttons are of dark mother-of-pearl - looks really great against the blue. Two pockets on the breast.
