Altering is almost always cheaper. The question is whether cheaper is the right frame.
The real question is which option gives you a better suit at a better price. And that depends on what you’re starting with.
A new suit at the lower end of the market — a high street option — costs anywhere from £100 to £300. A mid-range suit from a department store or online retailer, £300 to £600. A quality British suit, considerably more.
Against that, a standard set of alterations — trouser hemming, jacket sleeve shortening, waist suppression — might run to £60 to £80 total at a competent tailor. A more extensive set of adjustments, more. A full relining on top, more still. But rarely approaching the cost of a new suit.
Money.co.uk regularly covers cost-of-living comparisons across service categories in the UK and the conclusion for clothing consistently holds — repair and alteration costs a fraction of replacement in almost every category. Suits are no exception.
You have a quality suit that fits at the shoulders but needs work elsewhere. This is the clearest case. The fabric is good, the construction is sound, and the fitting issues are solvable. Altering it produces a suit worth wearing. Replacing it means spending the same money or more to get something of equivalent quality.
The suit has sentimental or practical value that a cheap replacement wouldn’t replicate. An inherited suit, a wedding suit, a jacket in a fabric that’s no longer available. These aren’t just about money.
The fit problems are minor. A trouser break that’s too long, sleeves that need shortening by a centimetre, a waist that’s slightly loose. These take minutes to fix and cost very little. Buying a new suit to avoid an £8.99 hem is obviously not the answer.
You’re between suits and need something quickly. A suit you own that almost fits, altered in a few days, beats waiting for a new suit to be ordered, arrive, and potentially need its own alterations.
The suit is cheap and the alteration would cost more than a modest percentage of its original value. A suit that cost £80 on sale and needs £70 of work is a borderline decision — you could spend £150 to £180 on a better suit that might fit more closely off the rack.
The shoulders don’t fit. Structural shoulder work is expensive. If the jacket sits badly at the shoulder and cannot be corrected without major reconstruction, the alteration cost rises significantly. At that point, a new suit that fits at the shoulder — and may only need minor adjustments — becomes the better investment.
The suit is in poor condition. Worn fabric, damaged seams, a lining that’s deteriorating in multiple places. Alteration improves fit. It doesn’t restore fabric. Putting money into a suit that’s past its best is rarely worthwhile.
This is where the calculation often tips towards alteration without people realising it.
A quality suit altered to fit looks and feels better than a cheaper suit that fits off the rack. The fabric is better, the construction is better, the weight and drape are better. A £400 suit adjusted by a tailor beats a £200 suit that needed no adjustments — every time.
The instinct to buy new when something doesn’t fit ignores the quality difference that money already spent represents. If the suit is worth keeping, alteration almost always produces a better result than replacement at the same budget.
Bring the suit in before deciding. Ourtailor in Angel at Arlington Way assesses the garment and gives you an honest quote before anything starts. We cover what’s achievable, what it would cost, and whether the investment makes sense on that specific suit.

For standard alteration work on a quality suit — yes, considerably cheaper. The exception is when shoulder fitting issues require structural work, which pushes alteration costs up significantly. A tailor can assess this before you commit to anything.
When the alteration cost approaches a significant proportion of the suit’s replacement value, or when structural problems make the outcome uncertain. A tailor should tell you honestly if you’ve reached that point.
Minor alterations on a cheap suit make sense if you need it quickly and the cost is low. Significant structural work on a cheap suit rarely makes economic sense — the alteration investment may exceed the suit’s value.
Done well, no. A skilled tailor improves the fit without compromising the fabric or construction. Done poorly, yes — rushed work or incorrect techniques can affect how the suit looks. Choosing a competent tailor matters as much as the decision to alter.
Trouser hemming. Low cost, quick turnaround, and one of the most visible improvements you can make to how a suit looks. Most off-the-rack trousers are too long — a £8.99 hem at Angelz fixes it immediately.
