i have a trouble with buying sweaters. for almost every single iteam at j.crew i go for items marked "LARGE" but it's kinda weird with sweaters. "LARGE" sweaters have the right lengths for my body but it fits maybe a bit too loosely around my waist and torso. i kinda wanna go for the more fitted look with sweaters but a medium might be too short for me to wear over untucked shirts with jeans. so, should i go for a large or a medium??
