How to measure
Wrap a strip of paper around the base of the finger, mark where it meets and measure the length in millimetres - that is the circumference, listed in the last column. Divide it by 3.14 for the approximate inside diameter. Measure at the end of the day when fingers are largest.
Dresses are sized on bust, waist and hip. Sets are sized on all three, because a two-piece has to fit at each. Take the size that fits the largest of the three. Dress and leg length vary by style and are listed on each product.
