A junior shirt fits smaller and tighter than a women’s shirt Matt Foley Motivational Speaker shirt . Ask your customer service specialist about this when ordering to make sure you get the best explanation of what style to order. If you wear a small in unisex then you might wear a medium in junior fit. Since junior fit is traditionally for pre-teen and teenage females, therefore it’s smaller than a women’s fit, so you should check this before you order. One brand we love here for this sizing is KingTee. They offers a women’s fit, but it’s not as tight as a junior fit. This more relaxed style can be dressed up and is a more fashion-forward, less traditional t-shirt look. KingTee goes into detail about their different fits like junior, classic, and curvy here.
