Most of our items are one size fits most and made to be worn loose. They are usually a M/L but adjustable to size down. Almost everything is made with some type of adjustable belt, strap, tie, or it will have an elastic waistband. You can find a sizing chart in the last photo of every item. We realize one size fits most will not always fit and will not look the same on every body type and that's why we have a great return policy. If it doesn't fit, feel free to send it back. We hope to add a range of sizes in the future. Please don't hesitate to reach out to us with any specific questions on sizing.
