Due to mostly all items being vintage on our website, sizing can vary. Overtime vintage clothing can either be smaller or larger than what is stated on the tag due to old age. We aim to provide as accurate sizing possible based upon modern day size references. If you have concerns about how an item will fit, we will provide EXACT measurements upon request. By comparing these measurements to your shirts at home you will be able to find the best size for you. Reach out to us on Instagram @ FishThrifts for any questions or measurements.
