For a church wedding, a registry ceremony, a reception or a cocktail evening, the suit is often the groom’s main garment, and the first decision is its basic form: a two-piece, a three-piece or a double-breasted suit. Each carries a different level of formality, suits different builds and behaves differently in Indian weather. Get this choice right and the details, colour, lapel and cloth, fall into place much more easily.
The Three Options at a Glance
| Two-piece | Three-piece | Double-breasted | |
|---|---|---|---|
| What it is | Single-breasted jacket and trousers | Two-piece plus a matching waistcoat | Jacket with an overlapping front and two rows of buttons |
| Formality | Flexible, from business to wedding | More formal and traditional | Formal, with a stronger presence |
| Warmth | Coolest | Warmer, from the extra layer | Warmer, from the double layer of cloth across the front |
| Best for | Most builds, warm venues, outdoor events | Air-conditioned venues, cooler months, long evenings | Taller or slimmer builds, receptions, cocktail evenings |
| Wear again? | Easily, for work and events | Yes, with or without the waistcoat | Yes, but it stays a statement piece |
The Two-Piece Suit
A single-breasted jacket and matching trousers is the most versatile suit a man can own and the easiest to wear well. It suits almost every build, it is the coolest option for a warm day, and it can be worn again at work or at other people’s weddings.
Buttons and buttoning
- One button: a clean, long line, common on dinner jackets and more fashion-led suits.
- Two buttons: the classic choice. Fasten the top button when standing and leave the bottom one undone.
- Three buttons: more traditional. The usual rule is sometimes the top, always the middle, never the bottom.
Unbutton a single-breasted jacket when you sit down and fasten it again when you stand, so it does not pull across the stomach.
The Three-Piece Suit
Adding a waistcoat makes a suit more formal, gives it a finished look even when the jacket comes off, and adds a place for a pocket watch chain or a contrasting back lining. For a wedding it has one particular advantage: once the reception is under way and the jacket comes off, the groom still looks dressed rather than half-dressed.
How a waistcoat should fit
- Length: long enough to cover the trouser waistband completely, with no strip of shirt showing between the two.
- Rise: a waistcoat works best with trousers that sit at or near the natural waist; low-rise trousers leave a gap.
- Fit: close to the body without pulling into creases around the buttons, and adjustable at the back.
- Neckline: the top of the waistcoat should show just above the jacket’s buttoning point.
The bottom button
Convention says the bottom button of a waistcoat is left undone. The popular explanation credits King Edward VII, whose girth supposedly prevented him fastening it; a trade magazine did mention the King’s unfastened button in 1908. As Gentleman’s Gazette’s account of the tradition notes, though, the story is more complicated: others wore their waistcoats that way before him, and photographs exist of the King with every button fastened. Whatever its origin, the convention has stuck, and many waistcoats are now cut to be worn that way.
Wear braces rather than a belt with a three-piece where you can. A belt buckle under a waistcoat creates a bulge, and braces keep the trousers at the right height so the waistcoat covers the waistband.
The Double-Breasted Suit
A double-breasted jacket has a wide overlap at the front and two columns of buttons. It usually has peak lapels and has a stronger, more architectural look than a single-breasted jacket. It developed from naval reefer jackets and, as The Rake’s guide to the double-breasted jacket describes, it was at its height in the 1930s and 1940s before returning to fashion in recent years.
Button configurations
Double-breasted jackets are described by the number of buttons and the number that fasten:
- 6x2: six buttons, two of which fasten, with the top two set wider for display. The classic, most formal configuration.
- 6x1: six buttons with only one fastening, giving a longer, lower lapel line.
- 4x2: four buttons, two fastening. Slightly more relaxed and modern.
- 4x1: four buttons, one fastening, with a low buttoning point that can make the torso look longer.
Wearing it
A double-breasted jacket is meant to stay buttoned while you stand, because the overlapping front looks untidy when it hangs open. Most have an internal button, often called the jockey button, that holds the underlap in place; fasten it too. Unlike a single-breasted jacket, many men leave a double-breasted one fastened when they sit, provided the fit allows it.
Lapels, Colours and Cloth for Each Style
- Two-piece: a notch lapel is the everyday default and suits business wear afterwards; a peak lapel makes the same suit more formal for a wedding.
- Three-piece: notch or peak lapels both work. The waistcoat can match the suit or, for a more festive look, come in a contrasting texture such as a jacquard or a lighter shade.
- Double-breasted: almost always a peak lapel, which balances the wide front. Textured cloths such as flannel, hopsack or a subtle herringbone suit the style particularly well.
For colour, navy and charcoal are the safest foundations for all three, mid-grey and ivory suit daytime and church weddings, and midnight blue looks especially rich for an evening reception. If the reception is black tie, the same choices exist in evening wear: a single-breasted dinner jacket, one worn with a low-cut evening waistcoat or a cummerbund, or a double-breasted dinner jacket, which needs neither because it stays buttoned. Our tuxedo collection covers the evening versions.
Which Suits Your Build?
| Build | Good choices | Why |
|---|---|---|
| Tall and slim | Double-breasted, three-piece | Both add visual width and structure |
| Shorter | Two-piece with two buttons, or a 6x2 double-breasted with a higher buttoning point | A single, uninterrupted line looks taller |
| Broad or athletic | Two-piece, three-piece | A clean single-breasted front avoids adding bulk |
| Fuller stomach | Two-piece single-breasted, or a well-cut three-piece | A waistcoat that fits smooths the line; a double-breasted overlap adds volume |
Fit matters more than any of these rules. A double-breasted jacket that fits perfectly flatters more builds than one that almost fits, because the overlap exaggerates any pulling across the front.
Weather and Cloth
Both the waistcoat and the double-breasted overlap add a layer of cloth over the torso, so in Indian heat the cloth has to work harder. A few choices make them comfortable:
- Lightweight cloth: for most of the year, a light to mid-weight worsted or a high-twist wool breathes far better than a heavy suiting.
- Half-lined jackets: leave the back partly unlined so air can move.
- A lighter waistcoat back: a thin, breathable back lining keeps a three-piece cooler.
- Venue: keep three-piece and double-breasted suits for air-conditioned halls, evening receptions and the cooler months, and choose a two-piece for a daytime outdoor ceremony.

Which to Wear to Which Occasion
| Occasion | Strong choice |
|---|---|
| Church wedding | Three-piece in navy, grey or ivory |
| Registry or small ceremony | Two-piece in a lighter colour |
| Reception | Double-breasted or three-piece in midnight blue, charcoal or a textured cloth |
| Cocktail evening | Double-breasted, or a two-piece in velvet |
| Engagement | Two-piece or three-piece |
| Work afterwards | Two-piece, or a three-piece worn without its waistcoat |
The Best of Both: Commission for Two Ways of Wearing
A three-piece suit is really three outfits: the full three-piece for the wedding, a two-piece for the office, and the waistcoat worn with odd trousers at a later function. If you want the formality of a waistcoat on the day and a suit you will wear again, it is often the best value choice. A double-breasted jacket, in turn, can be worn as a separate blazer with contrasting trousers once the wedding is over; see how a blazer differs from a suit jacket.
Common Mistakes
- A waistcoat too short to cover the waistband.
- Fastening the bottom button of a two-button jacket.
- Wearing a double-breasted jacket open.
- A belt under a waistcoat.
- A heavy three-piece for an outdoor daytime ceremony in the heat.
- Choosing a double-breasted cut in a size that almost fits.
