We try our best to include sizing guides for the customers convenience when shopping online. Most brands fit true to size, except for ICEDRESS items which tend to run a size small. However if you receive an item and are not satisfied with the fit you can certainly request a return or exchange if it is within the 30 day time frame as stated in our return policy. If you have any questions regarding fit for items you can refer to the sizing charts on our website or contact our customer service team for further assistance.
