Use these tips to measure yourself for a better size estimation. To calculate your sizing, you will need a soft measuring tape. Non-stretch string and a ruler will also work, but a measuring tape produces more accurate results. When measuring yourself, keep the tape firm, but not tight. Use your exact measurements when selecting your size.

Take measurements around the fullest part of your bust. This is a key measure for tops and dresses. It’s important not to tighten the measuring tape too much, the tape measure should fit snug and comfortably. Make sure it sits horizontally across your body and doesn’t dip down or run diagonally at any point.
Measure around the natural waistline – the narrowest part of your waist – keeping the tape comfortably loose. Stand as you normally would, do not suck it in or hold your breath.
Measure around the fullest part of the hips. This area should include your buttocks, so make sure to wrap your tape all the way around, without letting it ride up unevenly in the back. If you are unsure, take several measurements and use the biggest measurement. This measurement is important for trousers and dresses.
