The shirt that bulges out of the trousers

Short answer: A shirt bulges out when there is too much fabric around the waist, or when the layer underneath builds up. A close fitting vest and the right shirt size solve most of it.

Too much fabric

If the shirt is too wide at the waist, the fabric gathers over the belt. That is the most common cause.

The layer underneath

A loose t-shirt under the shirt creates folds that push the shirt out. A close fitting vest lies flat. See bamboo vest for men.

The length

A shirt that is too short is pulled out of the trousers when you move. Measure the length. See the size guide.

The material

A fabric with drape lies closer than a stiff one. See bamboo shirt for men.

The belt height

If the trousers sit low, there is more shirt to tuck away. That makes the problem worse.

Washing

The shirt is hung up straight after washing so the creases fall out. See the washing guide.

Frequently asked questions

Why does the shirt bulge out?

Because there is too much fabric at the waist, or because the layer underneath builds up folds.

Does a vest help?

Yes, if it fits closely. A loose t-shirt makes it worse.

Should I choose a smaller shirt?

Only at the waist. The shoulder width still has to fit.
