Every man has a garment in his closet that almost fits. The shoulders are right, the fabric is good, the style still works — but the waist is too full, or the sleeves are an inch too long, or the trousers pool at the ankle. It hangs there, unworn, while he debates: should I get it tailored, or should I just replace it?
It's a genuine question, and the answer isn't always obvious. Tailoring can rescue a good garment, but it can also throw good money after bad. Replacing can solve the problem decisively, but it can also waste a perfectly salvageable piece. The decision deserves a framework — not a gut feeling. Here's the one I use, built around a single concept: cost-per-wear.
The Core Concept: Cost-Per-Wear
Cost-per-wear (CPW) is the total cost of a garment divided by the number of times you'll wear it. A £200 coat worn 200 times has a CPW of £1. A £30 shirt worn 5 times has a CPW of £6. The coat was more expensive upfront but dramatically better value. CPW is the lens through which all wardrobe decisions — buying, tailoring, replacing — should be evaluated.
Applied to the tailor-vs-replace question, CPW reframes the decision. The question isn't "Is the tailoring expensive?" It's "Will the tailoring result in a garment I'll wear enough to justify the cost?" A £30 alteration on a blazer you'll wear 100 more times costs £0.30 per wear — exceptional value. The same £30 on a shirt you'll wear twice costs £15 per wear — a waste.
Don't ask whether tailoring is expensive. Ask whether the garment, post-alteration, will earn its cost back in wear. That's the only question that matters.
The Five-Factor Assessment
Before calculating CPW, assess the garment against five factors. If any factor fails, replacement is likely the better call.
1. Fabric quality
Is the fabric worth investing in? A well-made garment in quality fabric — substantial wool, long-staple cotton, full-grain leather — deserves tailoring. A thin, cheaply made garment doesn't, because the fabric will fail before the tailoring pays off. If the fabric is pilling, thinning, or showing shine at friction points, the garment is at the end of its life regardless of fit.
2. Construction quality
How is the garment built? A fully canvassed jacket with pick-stitched seams and quality lining is worth altering. A glued-together, fused garment from fast fashion is not — the construction won't survive the alteration, and it wouldn't have lasted much longer anyway. Look at the seams, the lining, the buttonholes. Quality construction is visible.
3. Shoulder fit (the dealbreaker)
If the shoulders don't fit, walk away. As we covered in the dress shirt fit guide, the shoulder seam is the hardest thing to alter on any garment. On jackets, it's essentially impossible without reconstructing the garment — the cost would exceed the value. If the shoulders are wrong, no amount of tailoring will save it. Replace.
Shoulders right, everything else adjustable: tailor. Shoulders wrong: replace. No exceptions. This single rule eliminates 80% of bad tailoring decisions.
4. Style longevity
Will you still want to wear this garment in five years? A classic navy blazer, a white Oxford shirt, a pair of grey wool trousers — these are timeless. Tailoring them is an investment in pieces you'll wear for years. A trend-driven garment — skinny lapels, an unusual colour, a dated cut — isn't worth tailoring because you won't want to wear it regardless of fit. If the style is dated, replace with something timeless.
5. Emotional value
This is the intangible factor. A garment with sentimental value — a father's old jacket, a gift, a piece from a memorable trip — may be worth tailoring even if the CPW math is marginal. Don't ignore emotional value, but don't let it override the other four factors. A beloved jacket with blown-out elbows and a dead lining can't be saved by tailoring alone.
The Cost-Per-Wear Calculation
Once the five factors pass, calculate the CPW of tailoring. The formula is simple:
CPW = (Tailoring cost) ÷ (Estimated additional wears)
Let's work through examples:
| Garment | Alteration | Cost | Est. Wears | CPW | Verdict |
|---|---|---|---|---|---|
| Navy blazer | Take in waist, shorten sleeves | £60 | 150 | £0.40 | Tailor |
| Wool trousers | Hem | £15 | 80 | £0.19 | Tailor |
| Dress shirt | Take in waist | £20 | 40 | £0.50 | Tailor |
| Cheap blazer | Take in waist | £45 | 10 | £4.50 | Replace |
| Trend jacket | Shorten sleeves | £35 | 5 | £7.00 | Replace |
As a rule of thumb: if the CPW of tailoring is under £1.00, tailor. If it's between £1.00 and £3.00, consider it carefully based on the garment's importance. If it's over £3.00, replace — you can buy a new garment that fits for less per wear.
What a Tailor Can and Can't Do
Understanding a tailor's capabilities prevents unrealistic expectations and wasted money.
Easily altered (worth doing):
- Hemming trousers: The most common and cheapest alteration. Always worth it.
- Taking in the waist of shirts and trousers: Simple, inexpensive, high-impact. See the shirt fit guide for why this matters.
- Shortening sleeves (from the cuff): Straightforward on shirts and jackets, though jacket sleeves with working buttonholes are more complex.
- Taking in jacket sides: Slims the silhouette. Moderate cost, high impact.
- Replacing buttons: Cheap and transformative, especially swapping plastic for horn on a blazer.
Difficult or impossible (think twice):
- Shoulder adjustment: Essentially reconstruction. Cost-prohibitive on anything but heirloom pieces.
- Letting out (making bigger): Most garments don't have enough seam allowance to be let out significantly. If it's too small, it's too small.
- Changing the rise of trousers: The rise is set by the pattern. A tailor can't meaningfully change it.
- Altering leather: Leather can't be let out or taken in like fabric. Specialist leather tailors exist, but it's expensive and limited.
- Fixing fabric damage: Re-weaving and invisible mending exist but are expensive and rarely invisible. If the fabric is damaged, the garment is usually done.
The Decision Framework, Condensed
Here's the full decision process, in order:
- Do the shoulders fit? If no, replace. If yes, continue.
- Is the fabric and construction worth saving? If no, replace. If yes, continue.
- Is the style timeless enough to wear for years? If no, replace. If yes, continue.
- Can a tailor fix the specific fit issue? If no, replace. If yes, continue.
- Calculate CPW: tailoring cost ÷ estimated wears. Under £1.00, tailor. Over £3.00, replace. In between, use judgment.
When to Replace
Replacement is the right call when the garment fails the five-factor test or when the CPW of tailoring is too high. But replacement has its own logic: don't replace a failed garment with another marginal one. Replace with something that won't need the same decision in two years.
That means buying quality construction, choosing appropriate fabric weights, selecting timeless colours and styles, and getting the fit right from the start — including having the new garment tailored if needed. A well-chosen replacement, properly fitted, will outlast two or three cheap replacements. The CPW of buying right once is almost always lower than the CPW of buying cheap repeatedly.
This is the deeper point behind the framework: the goal isn't just to make good tailor-vs-replace decisions. It's to build a wardrobe where the question comes up less often — because you've chosen garments worth keeping, fitted them properly from the start, and maintained them well enough that they don't reach the decision point prematurely.
A well-built wardrobe, in the end, is one where most pieces earn their place through years of wear. Tailoring is the tool that gets them there. Replacement is the decision that clears the way for better pieces. Both, used wisely, serve the same goal: fewer garments, better chosen, worn longer.
