Button or Clip, Suit, Tuxedo, Casual

The short answer

Suspenders hold trousers up from the shoulders, which is why they suit trousers that sit high on the waist and do little for trousers already held by a belt at the hips.

He Spoke Style’s guide gives the two rules in two sentences: “Suspenders should be fastened with buttons. Period. End of discussion.” and “Don’t ever wear suspenders with a belt…Choose one method or the other.”; Bespoke Unit agrees on both, “NEVER a belt”, and adds the trouser rule: “Trousers worn with suspenders will not have belt loops”, the “Trouser Rise Should be High”, and the waistband should be looser so the trousers float.

JJ Suspenders’ style guide sets the formality scale: “the skinnier the suspender, the more casual the look, while at the wider end of the spectrum, they become classic and even formal”, button-on braces are “considered a tad more formal than clip-ons”, and for business “a pair in a more classic hue (navy, black, taupe) that coordinates with the color of your shoes”.

The rest of this page is the types, the method for attaching and adjusting, the suit, waistcoat and black-tie rules, the casual version, and the mistakes.

The types

Button, clip, X and Y

JJ Suspenders’ feature guide lists the trade-offs in plain terms: clip-ons are “easy to wear & remove” but “can damage trouser fabric over time” and are “not appropriate for very formal situations”; button-ons “always look elegant and appropriate, no matter the occasion” but “need to sew buttons into trousers”; the Y-back is “more formal, and perfect for business, semi-formal, or formal occasions” and the X-back is “more casual, sturdy, work-appropriate”; non-stretch braces are “often more refined and elegant”, stretch ones “best suited to more casual occasions”.

Bespoke Unit’s preference is that suspenders be “either 1.25″ or 1.5″ wide”, which it argues avoids a costume look, with the adjustment buckles resting “pretty much right in the center of the torso”. The buckle position is a comfort setting; the width is that source’s taste, shared by most tailors, rather than a requirement of the garment.

The method

How to attach and adjust suspenders

Step one, the buttons: button-on braces need six buttons inside the waistband, two at the front on each side of the fly about two inches apart, and two at the back on either side of the centre seam; most suit trousers with side adjusters have them, and any tailor sews them onto trousers that do not.

Step two, the back first: with the trousers on, fasten the rear tab (Y-back) or tabs (X-back) to the back buttons, with the leather tab’s holes over the buttons and the strap running straight up the spine.

Step three, the front: bring the straps over the shoulders, keeping them flat and parallel, and fasten each front tab to its pair of buttons; the straps should run over the middle of each shoulder, not at the neck and not at the shoulder point where they slide off.

Step four, the length: slide the adjusters until the trousers sit at the natural waist with the braces holding them there and no more; He Spoke Style’s description is “a balance point between being too loose and too tight”, and the test is that the waistband stays put when you sit and the straps do not pull the trousers up into the crotch when you stand.

Step five, the adjusters: they sit on the chest, below the collarbone, at about the same height on both sides; Bespoke Unit’s centre-of-the-torso guidance is the usual starting point, and a shorter man on one-size braces will end up with them lower. Comfort and a strap that stays on the shoulder decide the final position, not the measurement.

Clip-ons: the same order (back, then front, then length), with the clips gripping the waistband about two inches either side of the fly and either side of the centre back seam; open the clips fully so the teeth do not chew the cloth.

With a suit

Suit, waistcoat and dinner jacket

With a two-piece suit: braces under the jacket, seen only when the jacket is off; He Spoke Style’s rule is that “a pair of suspenders is not an accessory that’s meant to be flaunted”, and the trousers are, in his words, “best on pants that have a little room in the waist”.

With a three-piece suit: braces go under the waistcoat, so the waistcoat sits flat over a clean waistband and the braces are not seen. The waistcoat’s bottom button stays open by convention, and the waistcoat has to reach the top of the trousers, which is the practical reason the trousers sit at the natural waist.

With a dinner jacket (tuxedo): braces are the expected support, in Bespoke Unit’s words “de rigeur with formalwear”, “traditionally the braces are white” and a belt with formal attire is, in He Spoke Style’s words, “a non-starter”; white or cream boxcloth or silk with white tabs, under the waistcoat or cummerbund, never seen.

With a blazer or sport coat and odd trousers: braces work when the rise is high enough for the trousers to hang. Chinos with belt loops will still take button-on braces once buttons are added, and the empty loops are simply visible; whether that bothers you is a preference, and a belt is the simpler answer if it does.

The shirt: braces sit over a tucked shirt, never under it, and the shirt is long enough to stay tucked because the trousers no longer grip it; a shirt with a soft collar and a tie takes braces best, and the tie’s colour family, not its pattern, is what the braces pick up.

Casually

Suspenders with jeans and casual trousers

The casual version exists and works when it is deliberate: clip-on or button-on braces, 1 to 1.25 inches, in a plain colour or a quiet pattern, on jeans or cotton trousers that sit at the waist rather than the hips, with an oxford shirt or a T-shirt, and no belt.

JJ Suspenders’ guide places clip-ons here, where they “look especially snazzy with city-shorts, funky jeans” in its words, and the Y-back is “considered the more up-to-date and on-trend” of the two backs.

What usually keeps it from reading as costume, in the writer’s judgement rather than as a rule: one pattern at most, braces or shirt; not repeating the braces’ colour and pattern in a hat or a bow tie, which is what makes an outfit look assembled from a theme; and a jacket over them outside casual settings. None of this is a correctness test, and men who dress deliberately around period clothing break all of it on purpose.

The one that genuinely does not work is low-rise jeans, because braces pull a low rise up into a shape it was not cut for. A belt as well is redundant rather than unworkable. Width against build is preference: a wider strap spreads the load and a narrower one is lighter, and men of every build wear both.

Mistakes

What actually goes wrong

Braces and a belt together, which duplicates the job and which Bespoke Unit reads as “an air of extreme pessimism”. That is one menswear writer’s reading of it, not a general verdict.

Clip-ons with a suit, which mark the waistband and read as a costume from across a room.

Trousers on the hips: braces on low-rise trousers pull the seat up and the crotch with it; the rise must be high enough for the trousers to hang from the shoulders.

Straps too tight, which lift the trousers with every step, or too loose, which let the waistband drop and the shirt billow.

Braces deliberately on show with a suit at a formal event, which the convention treats as an accessory worn out of place; in practice they are seen when the jacket comes off, and that passes without comment.

For the trousers themselves, the dress trousers guide covers the rise and the fit, and the black tie guide covers the evening outfit the braces belong to.
