These soft and comfy Bella + Canvas shirts are high quality unisex shirts. The adult shirts are unisex sizing with a semi-fitted cut (so they are slimmer and more fitted for men and a little loose and flowy for women). I normally wear the same size in these shirts as I do in womens. This works great over leggings or with jeans. Ladies who want a more fitted look might consider choosing a size down. Please see the sizing chart with measurements from Bella in the photos. You can take your favorite comfy shirt, lay it on a flat surface and compare the measurements of your fav shirt to the manufacturer's specs on their sizing chart.
