Most items have a sizing chart tab alongside the description.
If you need further assistance, email firstname.lastname@example.org with the item you'd like to purchase and the best available information about the size of the person you are purchasing the item for and we will do our best to assist you. Sizing charts are to aid you in the picking the correct size, but many factors go into the perfect fit and the sizing chart is not guaranteed to provide the correct size.
1. If you are in between sizes, select the larger size. Uniforms can be hemmed and altered to be made smaller.
2. Different manufacturers use different sizing charts. Don't exclusively rely on your current uniform size, unless you are purchasing the same brand uniform.
3. Headgear - if your headgear is pulling at your hair, wear a bandana and it will fit better.
