As a rule of thumb, your SParms size should correlate with your Polo shirt size (both for males and females). I.e. if you wear a size Small shirt, you will be a Small in SParms, etc.

If in doubt, err on the side of being smaller as being too big may lead to the top of the SParms slipping down marginally.
