Example: Let’s say your body bust is 39" & your waist is 35". In that case, we recommend ordering a size 40 - L if you like a regular fit. If you prefer a looser fit, you can go for size 42 - XL. You should also consider your hip measurement. When you order outfit size 40 - L, the actual measurements of the garment will be approx 40" at the bust & approx 36" at the waist.
