With this brand of clothes I would recommend you size up because the clothes run small! I sized all the way up to the biggest size they have. So do what I did and size up for a bigger and more comfortable fit! But other than that I have no complaints about this shirt! It’s really pretty and it’s comfortable! The material is mostly cotton but it does have a slight stretch to it so it’s not fully cotton material! But go buy itttt you won’t be disappointed!
