I know it can be frustrating, my daughter is 115 pounds and wears anywhere from a 2 to a 7 depending on the brand and the cut. I just have her try everything on because even the same brand one will be big and one small.

Someone said they cut through stacks of clothes at the factory so that attributes to the difference in the same brand and style fitting different.

I've told her it doesn't matter (she was so bummed the last pair of jeans was a 7) what the size is but that they fit her well, she's in good shape, has a nice figure.

Still doesn't it make us feel nice if we can just run in and grab a size 10 and know it will fit beautifully when we get home??
