We do not have a size chart as we carry many different brands and styles and they all fit differently. We do try to put sizes and descriptions on fit with each item page. If you need further assistance with sizing you can email us at firstname.lastname@example.org.
WE DO HAVE PLUS SIZES UP TO XXXLARGE! Most Crazy Train brand items we carry small-xxxlarge.
Here is a general size chart if you need a reference.
