Braces: why a tuxedo needs them

High-rise tuxedo trousers need braces because the straps hang the trousers from the shoulders, holding the waistband at the natural waist without squeezing the stomach. The legs then fall straight, the front crease stays clean when you sit, and you do without a belt, which breaks the line of formal wear. For an outfit worn through a whole evening, braces are more practical than most men expect.

Why high-rise trousers need to be hung

Low-rise trousers sit on the hips, held by the pelvis and a belt. Tuxedo trousers cut high sit in a different place: the waistband circles the natural waist, where there is no bone to rest on. If only the snugness of the waistband holds them, they either bite too hard or slide gradually toward the hips after hours of sitting and standing.

Braces fix this by carrying the weight on the shoulders. The waistband only has to fit, not grip, and it stays put all evening. The visible result is a held shape: the front crease runs straight, the seat does not sag and the leg falls cleanly to the shoe. The case for a higher rise is laid out in high or low tuxedo trouser rise.

Braces also replace the belt, a topic of its own in should you wear a belt with a tuxedo.

Button-on or clip-on

Braces attach to the trousers in two ways.

Type	How it attaches	Notes
Button-on	The strap ends have buttonholes that fasten to small buttons sewn inside the waistband	Neat and secure, nothing shows outside; the traditional choice for formal wear
Clip-on	The strap ends have metal clips that bite on the edge of the waistband	Convenient and works with any trousers; clips can slip or crease the cloth edge

For a tuxedo, button-on is preferred because it holds the waist steady and leaves no marks on the cloth. Made-to-measure trousers are usually fitted with the buttons inside the waistband, commonly two at the front and two at the back on each side, so you only need braces with buttonholes. If your trousers have none, a tailor can sew them in.

Clips suit a rental or borrowed outfit that has no buttons. If you use clips, choose a small-toothed type and grip the inside edge of the waistband, never the outer face.

X-back or Y-back

The back of the braces comes in two forms.

• Y-back: the two straps come together behind into a single band that connects to the back waistband with one button or clip. The back is flat and neat, and it usually goes with button-on braces. Under a shirt, a Y shows least.
• X-back: the two straps cross in the middle of the back and then split to two attachment points. This is more common with clip-on braces; it feels firmer but the crossing is thicker.

Both work. Under a thin shirt, or when you take your jacket off to dance, the Y is cleaner. How the braces look once the jacket is off is covered in when the jacket comes off: shirt and braces.

Colour: black, white or quiet

On a tuxedo, braces are not for show. They sit under the jacket, so the right choice is to keep them quiet.

• Black: the default for black and midnight blue tuxedos. Black satin or silk braces in the tone of the trousers do not show when the jacket opens.
• White: traditionally for white tie, with a white waistcoat and a wing-collar shirt. With a tuxedo, white braces show through a thin shirt and expose the line of the straps.
• Other quiet options: braces in the colour of the trousers, or a fine woven strap of moderate width with no large pattern and no heavy metal hardware.

Bright or printed braces are fun and suit a relaxed party, but they do not belong at a serious black-tie dinner. A medium-width strap suits most builds; a very wide strap tends to look mannered.

From the Mon Amie workroom

Braces only work when the waistband is cut to the right height and the buttons are sewn on firmly, so decide at the measuring stage. You can book a fitting at a showroom and let an advisor put you in high-rise trousers with braces, checking how they feel sitting, standing and raising an arm before you commit.
