Between dress sizes? It is always best to go up one! It's easier to take in a dress. You can't always let it out.
Never ever guess your size in special occasion dresses.
Measure carefully before you buy any plus-size gown.
You probably wear a different size in plus size formal dresses then in everyday clothes.
Your bra size is not your bust size. Your bust size is the fullest measurement around your back and cups in the front of your body.
Measure wearing the underwear you will wear under your dress.
Use a cloth tape measure; leave the metal one for construction jobs.
Have a professional tailor or seamstress measure you or ask a friend or family. You'll be glad you did.
Plan on alterations for a perfect fit. Everyone needs them!
