It looks very similar to Zara's. You can buy without fear. There was no size description when I bought it; I took M and had to adjust the waist and bust, but the length was almost too short (I weigh 58kg and am 1.66m tall). The order was shipped very quickly; I only had a problem with the delivery by the courier in my city, who left it at the wrong address.

Wow girls, a rare and comfortable dress, hurry up to buy it, it arrived to me in a week!
