Measure your waist, as the belt doesn't have much "give" since it is pvc. But you can adjust by changing the placement of the magnetic closure. Note that you can measure your waist over a shirt or over a thick sweater.
Inspiration: I have always loved big dresses and enjoyed pairing them with amazing belts. I never had the perfect belt, because most of the time the belt stood out too much when I wanted just a simple "waist cinch". I designed the Aviv belt for this exact purpose. It's clear so it can match any outfit, and it give the dress a really cool subtle look. It was so popular that we kept adding colors and widths. This is a belt you will wear over and over (until your friend steals it)!
