I'm roughly 5'3" and 130 lbs and ordered this shirt in a medium and it fits perfectly. I like that the shirt is long enough to not show off any skin above my jeans when I bend over or raise my arms (something that is rare to find in the latest fashions) and that the V neckline isn't too low or wide-set to show any part of my bra.
I do usually wear a small in t-shirts and decided to get a medium since I didn't want it to show off my mom belly roll too much, and I'm glad I did, so I recommend sizing up if you are worried about this issue as well. If you have a nice flat stomach though, then you'd be fine ordering your usual size or even a size smaller.

I purchased a medium and it fits perfectly. It’s very flattering.

Such a cute comfortable shirt! I range between medium and large and this shirt is close fitted for me in a size large. It fits my broader shoulders just fine.

Love the shirt! It’s comfortable and breathable. I purchased one last month, and loved it so much I purchased another. I only wish there were more colors to choose from.

I have a Florida trip coming up and this is perfect! I hate a sweaty cotton when it is hot. It fits great and looks great too.

I’m 160 lbs usually size M and 5’6 this shirt is very soft. I wear a vest over it as a part of my flight attendant uniform and it’s not too see thru. The sleeve is halfway between elbow and short wich is just right. Will be ordering more of those

No pic I’m wearing this tomorrow. This is a very nice shirt. It fits and well good. I’m5’5” 200lbs 42 D with stomach. I purchased a 2x and again its a nice shirt. I look good in this top. I’m wearing it under a blazer. The buttons budge just a tiny bit because of my breast.
