Scroll to the bottom to see our tips on sizing.  There are two size charts below, one chart is displayed in cm, and the other is displayed in inches.

Tips on how to choose your size.  Here is an example. You measure yourself with these measurements:  height: 162 cm, chest: 85cm, waist: 68cm, hip: 98cm.  In this case, these measurements fall between sizes S to L.  You should choose your size according to the largest of these measurements.  In this case, since hip is the largest of these measurements, you would select size L for your size.  If your costume doesn't quite fit right in all areas, it can be altered.  You can take it to a local tailor and they will alter it to fit you perfectly. If your measurements are close to the next size up, then you should select the larger size.  It's always better to have a larger size that fits, than a smaller size that doesn't fit at all.  Larger sizes can always be altered with a tailor; if it's too small though, an alteration won't help.
