Why do my trousers or shalwar keep slipping down?
Trousers keep falling down when waist and hips are close in size, the elastic is tired, the fabric is heavy or the band sits in the wrong place. What to state.
InspirationNothing to hold them up
Trousers or a shalwar keep slipping down when nothing below the waistband is wider than the waistband itself. Usually the waist and hips are close in size, the elastic was cut too long or has lost its grip, the fabric is heavy enough to drag, or the band sits at a narrower place than it was cut for. Saying exactly where you wear it, how firm you want it and what it is made of fixes most cases.
Walking makes it obvious, because each stride pulls on the leg and the seat, and a loose band gives way a little every time.
Four reasons it happens
One of these is usually the main cause, though two often work together.
- Little difference between waist and hips. If your hips are not much wider than your waist, there is no shelf for the band to rest on, so it relies entirely on grip.
- Elastic too long or tired. Elastic cut to a loose length, or worn out by washing and heat, has nothing left to hold with.
- Heavy fabric. Velvet, khaddar, a lined trouser or a deep embroidered or lace hem all add weight that pulls the waist down as you move.
- The band sits in the wrong place. Trousers cut for your hips but pulled up to a narrower waist are loose there, and a short rise can drag the band down from below.
Why it happens more when walking
Every step lifts one leg, which pulls the back of the trousers downwards, and a full shalwar seat swings with your movement. Smooth fabrics also slide over a smooth kameez lining, so a slightly loose waist creeps down with each stride. If the waistband stays put while you stand and drops only when you walk or sit, the band is close to right and needs a little more grip, not a different size. If the back dips mainly when you sit, see why trousers pull when you sit down.
What to say on your order
Measure your waist exactly where you wear the band, and say where that is: at your natural waist, a little below or on the hip. Our trouser size guide lists the other numbers, and the trouser fit guide explains rise and length.
Then choose the waist. A firm, wide elastic grips better than a soft narrow one, a drawstring can be pulled as tight as you need, and elastic with a drawstring through it gives both; our comparison of elastic and drawstring waists goes through them. For heavy fabric, say so, so the waist can be made firm enough to carry it. For a fitted waistband that stands away rather than slips, see why a waistband gapes at the back.
A traditional shalwar is easy to have made to your waist this way. Send your notes with a stitching quote if you are using your own suit, as explained on the Stitching Only page.
Common questions
Why does my shalwar slip only when I walk?
Walking pulls the leg and seat down with each stride, and a full shalwar swings as you move. A waist that holds when standing but slips when walking needs a firmer elastic or a drawstring, not a smaller size.
Should the elastic be cut tighter?
A little firmer, yes, but not so tight that it digs in. A wider elastic spreads the grip and holds better than a narrow one pulled tight.
Can tired elastic be replaced at home?
Usually. Most elastic waists sit in a casing, and new elastic can be threaded through a small opening in the seam with a safety pin and stitched closed.
