Please note that all our current styles are in inches and indicate the length of the designs. Measurements should be taken from the shoulder down. Therefore if you measure 54 inches from your shoulder to your ankle you should choose a size 54. If you are between sizes such as a 55 go for the next size up which is a 56. 
If you are still unsure in regards to sizing or are simply in need more details please feel free to contact us at where we can assist you to the best of our ability.
