I love the way this top fits. It flows well and does not cling - very important! It packs well, too; no wrinkles. I got lots of compliments on it when I first wore it. I'm purchasing more in different patterns. For reference, I am 5' tall, weigh 175, and bought XL. My weight is distributed all over; normally I wear L but XL was perfect. I am very hard to fit, being short, but the sleeves on this were fine, not too long.
