I ordered a medium . Iβm 5β4 at 146lbs. I LOVE THIS! Itβs perfect to wear during the summer here in FL. I loved the set so much, so I ordered another in the red! Also, ordered a navy set for my sister in law. She saw it on me & loved it! I donβt put it in the dryer, and it dries beautifully! Definitely worth it!I hope this helps!
