Button down Blouse

Elegant long sleeve button down Blouse. Never worn only tried on. Sheer material so will need an under shirt for sure or a hot bra/bralette. Beautiful lace design down the sides of the shirt. Buttons are hidden under extra fabric. Not sure what 2XLT MEANS, but im busty (42C) and it would not close comfortably on me so id say its a maybe 12/14 size maybe size 16 small chested figure. Material: Blouse is 100% polyester and lace is 100% Nylon Measurements: Bust is 22 inches
