The sizing at Priestess + Deer does not reflect the sizing of most mainstream stores. We have done our best to do a reflection of how we see women.  Keep in mind, most of our fabrics are stretchy and most of the clothing is draped to fit many bodies. Because of these factors, you may go up or down in sizing depending on how you want the garment to fit. All of the products should indicate how the clothing will fit according to these sizes. This is not haute couture you do not need to fit the garment to the exact inches indicated. 
Please be in touch if you do not see your size here. We are more than happy to do custom work whenever possible, which is almost always, without a big added charge.
