Below is a general guide for your reference.
We carry several brands so sizing can vary between products. We always try to list within the item listing if sizing runs generous, small, or true to size. Please see each item description for more details. If you are between sizes, we recommend going up a size. If you ever have a question on how sizing runs on a particular item, please e-mail email@example.com
Bust: Measure the fullest part of your bust and make sure the measuring tape fits comfortably.
Waist: Make sure the measuring tape fits comfortably around the narrowest part of your waist.
Hips: Place the measuring tape around the fullest part of your hips/thighs, with the tape fitting comfortably around your body.
