The most common option is to wear a belt.
I would advise giving preference not only to leather but also to interesting versions with chains.
Wearing wide belts or corsets will not only help to accentuate the waist, but also make you visually slimmer."
The use of contrasting colors V-neck dress with straps will help you look slimmer I would recommend combining cardigans and sweaters with high-waisted pants. Short tops, jackets, and shirts will also help accentuate the waist.
