Cotton Blend Trench Coat

I ordered this in the XS and S, and so far, only the Small came in, but it is too large. As reference I am 5'5" and 117. but very small framed. I ordered several of the Mango and I thought I would like this best, but it is very heavy in weight, which is not the most comfortable. Also, I now realize that for me, having all the flaps and epaulets and buckles is too overwhelming for a small- framed person. I prefer another Mango one I ordered that is a cleaner, more streamlined look. Also, these sleeves are narrower so, for me, layering things underneath would feel too constraining. I have always lived in warmer climates so not one who likes that feeling of being bundled up and constricted. I am going to go with a lighter weight that to me has a nicer drape and more comfortable to put heavier layers on under.
