Seriously haven’t taken it off since I got it. It’s a great winter shirt. I would say it’s perfectly true to size and not too tight of a fit. I’m typically a medium (5’2”, 130ish lbs, 32DDD) and that’s what I got and it’s perfection. You can fold the neck in half (and even in half again for a almost more of a mock turtleneck look) or just wear it scrunched up around your neck instead of folded and it’s not too tight but does keep you warm. Very pleased with this purchase.
