Designer top made in Japan similar top selling on Poshmark for $320 with an original price of $1,100. Front is Excellent Quality Cotton with stretch and back is flowy polyester. ❤️ its just not my size. I have noticed this brand goes by sizes 1 ,2, 3, 4 .Size 1 is xsmall. But I conclude this top is best for medium .I am size large, and it is a little snug in arms on me. It fits fine everywhere else because it has the flowing back. Poshmark suggested the price of $190.
