Without writing a book… I’m 5’3, 225 lb, 38g bra. I do XL/1X in FN and after reading reviews I went with a XL. The jacket actually fits ok but I cannot close it due to my large breasts. It doesn’t look too small, I can definitely pull it off wearing it open I just can’t button. The arms are LONG and come down to my knuckles. I have average normal arm length. I’ll figure that out bc that I don’t like. The quality is very good very well made. It doesn’t look cheap at all! The brown is more like a dark mushroom not what is on the model. In my opinion a 1X would allow me to button but it would have been an oversized look and the arms would have looked stupid. Hopefully this review helps in general especially if you’re in between sizes like me. It’s a beautiful jacket definitely worth the buy just try and get the right size based on how you like your jacket to fit. Sizing down may hurt you so be careful…
