To measure your chest, wrap a measuring tape around the fullest part of your bust, ensuring that the tape is level and not too tight. For waist measurement, measure around the narrowest part of your waist. The length of the dress should be measured from the highest point of the shoulder down to the desired hemline. Finally, the swing measurement is taken around the fullest part of the hips to ensure comfort and movement. Accurate measurements will assist in selecting the best size for your body type.
