Answer I can only quote you from Canadian sizes for women. For example there are children's sizes then there are young woman's sizes and adult sizes. If you are on the large side of the Weigh Scale a size 15 would put you depening on how your body is stuctured in the 115 to 125 pound scale. If on the other hand you are a size 4 to 8 then you don't weigh more than 120 pounds depending on the cut of the clothes that you wear. If something seems too big, quite probably it is. Use your imagination see where that takes you and good luck.
