To belt an oversized shirt, decide whether the belt will sit over the shirt or pass through the trousers beneath it. The first shapes the shirt; the second gives a tucked outfit a visible finishing detail.

Set the volume before adding a belt
Button the shirt as you intend to wear it and let the hem settle. Check whether there is enough length for movement if you are wearing it as a dress.
Place your hands at the waist and gather a little fabric. If that already creates a large bundle, try a half-tuck or a shorter shirt instead of cinching harder.

Three workable outfits
White shirt and straight-leg jeans
Tuck the front section into the jeans and put the belt through their loops. Leave enough ease above the waistband to reach forward without pulling the shirt tight.
Keep the untucked sections relaxed. This approach shows the buckle without gathering the entire shirt beneath it.
Long shirt and tailored trousers
Wear a belt over the shirt near the waist, then distribute the fabric around the sides and back. Keep the button placket aligned unless you deliberately want an asymmetric effect.
A relatively simple buckle lets the contrast between the loose shirt and neat trousers carry the outfit.
An oversized shirt dress
Try a belt over the dress and lift a little fabric above it for a softer shape. Check the hem after this adjustment; pulling fabric upward can shorten the dress more than expected.
Walk, sit and raise your arms before deciding that the proportions work for the day.
Fix the most common problems
If the back balloons, release the belt and spread the gathers more evenly. If the front buttons pull, loosen the belt or move it away from the point of greatest tension.
If the belt keeps sliding down, the shirt may be too smooth for the chosen placement. Try a compatible design with more stable positioning rather than fastening it painfully tight.
Finish with one clear detail
A printed shirt often works with a quieter belt. On a plain shirt, a textured strap or distinctive buckle can become the main accent.
Check the side view as well as the front. The outfit should look intentional from different angles and still feel like a shirt you can move in.
