Suits and dresses altered at BTS National Stadium Exit 3 and 4, usually back in two to three days. Bring the garment and the shoes you will wear with it.

01

What we adjust

Most of what people bring in is routine:

  • A sleeve that covers the hand.
  • A waistband that no longer closes.
  • A hem that was never right.

What is possible is decided by the seam allowance — the spare cloth folded inside the seams — and that is a physical fact checked on the garment itself. The table sets out what is usually possible and what is harder:

Usually possibleHarder, or not worth it
Sleeve and trouser lengthShoulders — possible, expensive, often not worth it
Waist taken in or let outLetting out beyond the seam allowance
Jacket body taperedChanging a jacket’s length from the top
Dress hems, straps, bodicesRe-cutting a fused jacket

what can and cannot be altered sets out the limits.

Sleeves and length

Sleeves and trouser length are routine work, shortened or lengthened within the allowance the maker left. Bring the shoes you will wear — a trouser length measured over the wrong shoe is measured wrong.

Waist and taper

Taking in is more forgiving than letting out, because taking in only needs the seam and letting out needs cloth that may not be there. If your size has changed, resizing a suit you already own covers how far it goes.

Shoulders, and the limit

Shoulders can be altered. They are the most expensive alteration on a jacket and the one most likely not to be worth the money, and we will tell you that before you pay rather than after. A fused jacket limits it further — construction is decided when a suit is made, not when it is altered; that is why bespoke tailoring at the shop starts from a canvassed jacket.

How long it takes

Two to three days for most work; ask whether a simple job can be done sooner. how quickly alterations come back has the times by job, and what slows a job down.

The exceptions are delicate cloth, beading and linings, which are hand work and do not compress. Send a photograph on WhatsApp before you travel and you can be told which of the two your garment is.

If a suit or dress needs to be ready for a wedding, say so when you bring it in — the date decides the schedule as much as the job does. For a suit made new for the day rather than altered, see wedding suits for the groom and groomsmen.

What it costs

An alteration can be priced once the job is seen, because the job is visible before it starts: a hem is a hem. Bring the garment in, or send a photo on WhatsApp, and you get a number before any work begins.

Formal wear is the exception worth flagging before you bring it in: a dinner jacket is altered to tighter tolerances than a day suit. tuxedos and dinner suits covers what the shop makes new.

Bringing it in

  1. Bring the garment and the shoes you will wear with it.
  2. Try it on so the work can be pinned on you rather than guessed.
  3. Collect in two to three days, or sooner for simple work.

Bring whatever the garment will be worn with — a particular belt, a waistcoat, boots rather than shoes. A hem pinned over the wrong shoe is a hem that gets done twice. And try it on even when you are sure of the size: what is pinned on the body is what the finished garment matches, and a guess made across the counter is a guess you pay for.

For directions from MBK and the opening hours, start at the tailor inside National Stadium.

Dresses and bridal

Dresses are altered here too — hems, waists, straps and linings: dress alterations. A wedding dress is a different job with a different timetable: two fittings, the first about three weeks before the day — wedding dress alterations.

The difference between the two is the timetable rather than the work. An ordinary dress alteration runs like any other job on the bench. A wedding dress is fitted twice and timed against the date, because it is altered to the body that will wear it rather than to the body of two months earlier.

Questions people ask

How long do alterations take?
Two to three days for most work, which is the shop’s ordinary turnaround. Whether a simple job such as a trouser hem can be done sooner depends on what is already on the bench that morning, so it is worth asking rather than assuming. Delicate cloth, beading and linings all add time, because beads come off by hand along a seam and go back on afterwards. Send a photograph on WhatsApp to 085 048 7655 and you can be told before you cross Bangkok.
What does an alteration cost?
It depends on the job. Bring the garment in, or send a photograph, and you get a number before any work starts. That order matters: an alteration quoted on the garment in front of someone is a real number, and one quoted from a description is a guess. If the work would cost more than the garment is worth, you will be told that too.
Can you alter a suit bought somewhere else?
Yes, and most of what comes in for alteration was bought elsewhere. It makes no difference to the work. What does make a difference is the garment itself: how much seam allowance the original maker left decides how far it can be let out, and whether the jacket is canvassed or fused decides how well it will take the change. Bring it in and wear it, so the work is pinned on your body rather than guessed from measurements.
Can shoulders be altered?
Yes, and it is the one to avoid. The shoulder is where the sleeve, the canvas, the collar and the body all meet, so moving it means taking the jacket apart and rebuilding the thing that holds its shape. It costs more than most jackets are worth and the result is never quite as clean as a shoulder that was cut right. You will be told that before you pay. If a jacket is wrong in the shoulders when you are buying off the rack, that is the fit signal to walk away from.
What should I bring?
The garment and the shoes you will wear with it, every time. Try it on rather than leaving it over the counter, because work pinned on you is work that fits and work done to a description matches the description instead. For a dress, bring the underwear you will wear with it as well, since all three change where the garment sits. If several things need doing, bring them together: they are quoted on the garment and done in order.
Do you alter dresses?
Yes. Hems, waists, straps and shoulders, bust and bodice through the side and princess seams, linings and zips are all ordinary work here, and most of it takes two to three days. Silk, chiffon, lace and anything beaded are slower, because those cloths mark and a needle hole in silk does not close. Wedding dresses have their own timetable of two fittings, the first about three weeks before the day, which is deliberate: a dress altered months ahead is altered to a body that may have changed.
Can a suit be resized after weight change?
Usually by one to two sizes, decided by the seam allowance the original maker left inside the garment. Taking in is the easy direction because you are removing cloth rather than finding it. Letting out is limited by whatever inlay exists, which varies enormously and can be checked in about a minute by turning the garment inside out. Past one or two sizes, proportion stops you rather than the cloth: the pockets end up too close together and the armhole sits wrong.
Do I need an appointment?
No. Walk in any day between 10am and 9pm, including weekends. The shop is inside BTS National Stadium station at exits 3 and 4, beside MBK Center, so it is an easy stop on the way past rather than a trip of its own. If you cannot get there, send a photograph on WhatsApp first: some jobs can be assessed well enough from a photograph to tell you whether the journey is worth making.

What a customer said

5 out of 5 stars

We stumbled upon The Loft Tailors getting off the sky train going to MBK. The price of the suit was very competitive and the craftsmanship was great. My son went to the fitting appointment and needed slight adjustment. When we came back to fit again it was perfect. They also are very fast.
