I am 5' 1". I weigh 155 pounds. My bust is 42" (36 DD). My waist is 37". My hips are 43". I am in between a size medium and a size large. My measurements are almost the same as the model wearing the size large. However, I ordered this jacket in a size medium because I am much shorter than she is, I have a short torso, and I didn't want the sleeves to be too long. The medium size fit me perfectly. I cannot wear thick sweaters under it though. But I am ok with that. I didn't buy it to wear for the winter time, more for cooler/fall weather here in NY. It is a different style of jacket than I would normally wear/buy, but that's why I like it. Its a rich denim, not thin. I like that it has the snap on buttons, functional front pockets, and a belt. I had signed up for notifications and was able to snag it, as I missed out on it when it first came out. The ladies may be doing inventory and found some extra ones. Make sure you'll sign up for items that you like, that may have sold out. I cannot tell you how many times I've lucked out with being notified.
On another note: It would be great if ByEgreis can get more models in other sizes, other than just XS and small. Sometimes I see the large size model, but not always. This would help with seeing how the clothing fits on a larger model. Such a cute jacket!
