Cream dress with beautiful details

I bought this dress in Spain and foolishly cut out the tags because they rubbed. It has beautiful details with rushing and pleated layers, the skirt reminds me of a tulip. It’s a very flattering fit, I’d be keeping it if I could do the side zipper up 🙃. The outside of the dress is a crepe like material and the inside is like a satin. Measurements are in photos. The model is 160 lbs and works out regularly, it fits but it is tight on her, so my estimate of size S is so it’s a more comfortable fit.
