Beautiful sleeveless blouse

So my title is unaspiring, but trust me, this top is beautiful on! No tags whatsoever, but it feels like a cotton linen combo. Pleated front, mesh neckline, this is fantastic for a night out or under a blazer - very flattering! No size tag, please use measurements, I’d say it’s closest to a size large (for reference, I’m 5’10 sporting a 36DDD).
