These tops are perfect for women who are petite and have trouble finding scrub tops. I'm 5'1 and 105 lbs and scrub tops used to swallow me without alterations. I ordered an XS and can fit a thick tank top or long sleeve under it without a problem. They fit true to size. They are also not too long. Just long enough to cover your backside so when you bend down you don't feel like the patient's family can see everything, haha! The side panels aren't tight, they just create more flexibility in the material. If you hate tops that feel like they could stand up on their own or if your tired of paying a fortune for alterations then these are for you! So soft and durable! Cherokee did a great job!! I'll be purchasing more, thanks!! :)
