Here is the chart for standard Cry Cry Cry garments. DON'T GUESS!!! Measure yourself and compare to this chart. If your proportions vary more than a few centimetres from the standard sizing, use the option "I'll send you my measurements" and you'll get a much better fit!
For example if your bust is a size MED, but your waist is an XS (or XL), the only way to have a well -fitting garment is to use this option. This is a very good reason to buy your frocks from Cry Cry Cry!!!!
