Most guides to custom tailoring in Bangkok explain the process: the fittings, the measurements, how to find a good shop. Far fewer help you with the decision that actually faces you in the consultation chair, which is what suit to order in the first place.
Single breasted or double breasted. Two piece or three. A versatile business suit or something for a wedding. Notch lapel or peak. Navy or charcoal. These choices decide how often you will wear the finished garment and how well it serves you, and they are easy to get wrong when a tailor is waiting and a fabric book is open in front of you.
This is a practical guide to those choices. Louis Collections has been tailoring on Sukhumvit Road since 1985, and the guidance below reflects the conversations we have with buyers every week. For the tailoring process itself, for fabric, and for choosing a shop, see our companion guides.
Before any decision about style, answer one question honestly: what is this suit for? Almost every other choice follows from it.
A tailor who asks what the suit is for before discussing style is doing the job properly. The purpose should lead.
This is the first structural choice, and it sets the character of the whole suit.
Single breasted is the more versatile and the safer first choice. It has one column of buttons and a clean, understated front. It suits almost every body type, dresses up and down easily, and never looks out of place. For a first custom suit, single breasted is almost always the right answer.
Double breasted has two columns of buttons and an overlapping front. It is more formal, more structured and more distinctive. It flatters a taller frame especially well and makes a confident impression, but it is less casual and a stronger statement. It is an excellent second suit once you already own a versatile single breasted one.
If you are choosing your first custom made suit and want it to work everywhere, choose single breasted. Save the double breasted for when your wardrobe can support it.
The second structural choice is whether to add a waistcoat.
A two piece suit is a jacket and trousers. It is the everyday standard: practical, comfortable in warm weather, and appropriate for almost any business or social setting. For Bangkok’s climate in particular, a two piece is the more wearable choice for daily use.
A three piece suit adds a matching waistcoat. It is more formal and more visually complete, and it gives you flexibility, as the jacket can come off while the waistcoat keeps the look polished. It is a strong choice for weddings, formal events and anyone who wants a more traditional, layered appearance. The trade-off is warmth, which is worth considering in a tropical climate.
For a versatile first suit in Bangkok, a two piece is usually the more practical choice. A three piece is well worth considering for a wedding or for a buyer who specifically wants that fuller, more formal look.
Colour decides how versatile a suit is. The most useful suits are the least adventurous, which is why the classic business colours endure.
Colour | Character | Best For |
Navy | The most versatile suit colour there is | A first suit; business; weddings as a guest; almost everything |
Charcoal grey | Formal, understated, authoritative | Business; formal occasions; an excellent first or second suit |
Mid grey | Lighter, slightly less formal, very flexible | Business in warm climates; a versatile second suit |
Light grey or tan | Relaxed, warm-weather, less formal | Daytime weddings; tropical events; a later addition |
Black | Strictly formal, limited for business | Formal evening wear and specific formal occasions only |
For a first custom made suit, navy or charcoal is the wise choice. Both work for business, both work for weddings as a guest, and both photograph well. Black is widely misunderstood as a default business colour; it is in fact best reserved for formal evening wear.
Once the structure and colour are decided, a series of smaller choices shape the personality of the suit. A good tailor will guide you, but it helps to arrive informed.
None of these details needs to be adventurous. Restraint tends to age better than fashion. The aim is a suit that looks considered, not dated.
The single greatest advantage of a custom made suit over an off-the-rack one is fit. It is worth understanding what good fit means so you can discuss it clearly with your tailor.
A good Bangkok tailor will refine all of this across fittings. Your job is to stand naturally, speak up about anything that feels wrong, and resist a cut so close that it looks impressive standing still but pulls the moment you move.
Some occasions call for particular choices. A quick orientation:
If you expect to commission more than one suit, it helps to think a step ahead. A wardrobe planned in sequence is more useful than three suits chosen at random.
Commissioning in this order means every new suit adds range rather than duplicating what you already have. A tailor who keeps your pattern on file, as Louis Collections does, makes each subsequent order quicker and easier than the first.
Louis Collections has been tailoring custom made suits on Sukhumvit Road since 1985. Every suit is cut from an individual paper pattern, every fitting is handled by experienced tailors, and we take the time to guide buyers through exactly the choices set out in this guide, from structure and colour to lapels and fit.
We dress diplomats, business travellers, grooms, brides and clients who have been returning to us for decades. We keep patterns on file, so each suit you commission with us builds on the last. Whether you want a single versatile navy suit or a planned wardrobe, we are glad to talk it through before anything is decided.

Keep the first one flexible: a single-breasted two piece in navy or charcoal, notch lapels, a gently shaped line. That mix carries you through work, formal events and weddings as a guest, and it stays current far longer than a fashion-led cut.
For a first suit, single breasted wins on sheer adaptability. Double breasted is bolder and dressier, particularly good on a taller build, but it makes more sense once you already own a versatile single-breasted suit to anchor your wardrobe.
Day to day in the heat, a two piece is the more comfortable, more practical garment. The waistcoat of a three piece delivers a richer, more formal effect and earns its place at a wedding or for anyone who wants that layered, traditional finish.
Navy is the most adaptable shade going and the standout first choice, with charcoal a very close runner-up. Both cover business and guest-at-a-wedding duty. Black, despite its reputation, belongs to formal evening wear rather than the working week.
Start at the shoulders, the one area that cannot really be corrected afterwards; the seam should sit right at the shoulder’s edge. From there, a buttoned jacket should trace your shape cleanly, the collar should hug the shirt without gaping, and a little cuff should show below the sleeve.
Notch lapels are the all-purpose default on single-breasted business suits. Peak lapels carry more formality and confidence, natural on double-breasted suits and sharp for evening or wedding wear, while shawl lapels are dinner-jacket territory. A middling width lasts best.
A groom has licence to be more individual: a three piece, peak lapels, a midnight blue, a quiet texture. Aim for something that shows you at your most polished yet remains a suit you will genuinely reach for again afterwards.
Build it in a deliberate order. A navy single-breasted two piece comes first, charcoal second, and only then move into something more expressive, a pattern, a paler tone, a double-breasted cut or a three piece, so each addition widens your range instead of repeating what you have.
