This is a sleeveless dress from the American brand GYMBORee. It has a side zipper. It was very easy to wear and I loved it. The length from the shoulder strap to the hem is 88cm, and the narrowest width around the chest is 33cm. The size is listed as 150 because I started wearing it around the time I was wearing size 150, so please check the length, etc. Please note that the measurements are taken by a layman, so there may be slight errors. - Brand: GYMBORee - Size: 10 (150) - Design: Floral - Style: Sleeveless
