It is OK.
The romper does not look exactly like on the model.
It is little baggy and made of very thin material. It will be ideal on the beach but I would not wear it nowhere else. I am size 6 and bought Medium. It fits me well. I do not have problems to put it on or with a zipper. I take it with me to Costa Rica since it is very hot there and it will be ideal for me. Recommend only for the beach.
