Cotton dress from Mohito

I bought the dress at Mohito two years ago. I can't find the original photo. It is 100% cotton. There is a hidden zipper on the side. A wide belt sewn into the sides wraps around the body several times.
The top is like a blouse, and the sleeve length can be adjusted. The bottom is slightly puffy, but it's not a crazy princess dress situation. Worn once to formal events—a wedding and a graduation.

Shoulder width 39 cm Chest 44 cm Waist 37 cm Total length from shoulder 106 cm For context - I am 163 cm tall and usually wear size S/M. Riga Imanta or Pakomats.
