I’m so glad I sized up based on the 1 review at the time of purchase. I have really thick upper arms and broad shoulders & chest. The denim portion (sleeves/ shoulders) has absolutely NO STRETCH, but the sweater bottom is true to size, soft and stretchy,” and a lovely, delicate shade of dreamy light blue. Absolutely chic sweater jacket!💣💣 If you have a larger upper body and thicker arms, definitely size up and it will fit just fine. It fits comfortably and is so cute on. The 3 buckles across the top add a fashionable detail & vibe!🤩 Love it & can’t wait for cooler weather to sport it!♥️

the sleeves were so tight that I couldn’t even pull the sweater up. I’m going to return and get a large. my arms are very slightly bigger than the average person. they usually fit in a medium.
