Choose a single-breasted suit for versatility and everyday wear, and a double-breasted suit when you want a sharper, more formal statement. For a first or main suit in Singapore, single-breasted is almost always the right call; double-breasted is a confident second suit. This guide explains the difference and when to wear each. Made-to-measure suits start from $299; we’re rated 5.0 from 178 Google reviews.

The quick difference
A single-breasted jacket has one column of buttons and a small overlap of fabric at the front — the standard, most versatile cut. A double-breasted jacket has two columns of buttons and a wide overlap, giving a structured, formal, slightly retro look. Single-breasted is easier to wear and dress up or down; double-breasted makes more of a statement and is always worn buttoned.
Single vs double-breasted at a glance
| Single-breasted | Double-breasted | |
|---|---|---|
| Formality | Versatile — casual to formal | More formal, dressier |
| Best for | First suit, office, everyday | Statement, events, confident dressers |
| Worn open? | Yes, can unbutton | No — keep it buttoned |
| Climate note | Lighter, cooler (one layer overlap) | Warmer (extra fabric overlap) |
When to choose single-breasted
Single-breasted is the default for good reason: it suits every body type, every dress code, and you can wear it buttoned or open. For an interview suit, an everyday office suit, or your first made-to-measure suit, single-breasted is the safe, versatile choice. In Singapore’s heat it’s also a touch cooler, with less fabric overlapping the torso.
When to choose double-breasted
Double-breasted rewards confidence. It looks sharp for weddings, formal events and anyone who wants a distinctive, polished silhouette. It’s a great second or third suit once you have a versatile single-breasted navy. Keep it buttoned — a double-breasted jacket isn’t designed to be worn open — and note the extra fabric makes it a little warmer, so a lighter cloth helps in our climate.
What about body type?
Both cuts can flatter any build when made to measure. Single-breasted with a clean fit suits everyone. Double-breasted adds structure across the chest, which taller and slimmer builds carry easily; broader builds can wear it too with the right button stance and a lightly shaped cut — which is exactly what a made-to-measure fitting dials in.

Buttoning rules
- Single-breasted, two-button: fasten the top button only (leave the bottom undone); unbutton when seated.
- Single-breasted, three-button: “sometimes, always, never” — middle always, top optional, bottom never.
- Double-breasted: keep it buttoned whenever standing.
Which should be your first suit?
For almost everyone: a single-breasted navy. It’s the most versatile suit you can own and works for the office, interviews, weddings and dinners. Add a double-breasted suit later when you want a sharper, dressier option. Either way, the fit matters most — a made-to-measure suit is cut to your measurements so the cut you choose actually looks right. See bespoke suits and our men’s style guide.
Frequently asked questions
Is single or double-breasted better?
Neither is universally better — single-breasted is more versatile and the right choice for a first or everyday suit; double-breasted is more formal and makes a sharper statement.
Should my first suit be single or double-breasted?
Single-breasted, in navy. It’s the most versatile cut and works for nearly every occasion.
Can you wear a double-breasted suit open?
No — a double-breasted jacket is designed to be worn buttoned whenever you’re standing.
Is double-breasted too formal for the office?
Not at all in many workplaces, but it’s dressier than single-breasted; for conservative offices a single-breasted suit is the safer everyday choice.
Is double-breasted hotter in Singapore’s climate?
Slightly, because of the extra fabric overlap — choosing a lighter-weight cloth offsets it.
How much is a custom suit?
A made-to-measure 2-piece starts from $299 in either cut.
