Fit is the single factor that most determines whether a piece of clothing looks expensive or cheap, deliberate or accidental. A beautifully made garment in poor fit looks worse than a modest garment in perfect fit. This is not a subjective assessment — it is a consistent observation across decades of fashion writing, personal styling, and the visual evidence of comparing two identical garments on two different bodies where one has been tailored and one has not. The tailored version looks better. Every time.
The logical consequence of this is that alterations are one of the highest-return investments available to a wardrobe. Spending thirty pounds on a hem can make a pair of trousers that cost fifty pounds look like they cost two hundred. Spending forty pounds to take in the waist of a blazer can transform a piece that fits well in the shoulders but bags everywhere else into one that looks built for you. The economics of tailoring are more favourable than most people realise, and the results are more visible.
The Alterations Worth Doing
Hemming is the most common and most universally worthwhile alteration. Trousers, skirts, and dresses that are even slightly too long look unfinished and proportionally off; taken to the correct length for your height and the footwear you intend to wear with them, the same pieces look considered and correct. Hemming is also one of the least expensive alterations, particularly for straight hems without complex finishes. If there is a single alteration that most wardrobes should undertake more often, it is this one.
Taking in at the waist is the second most transformative. Blazers and jackets that fit in the shoulder but have excess fabric at the waist can be nipped in to create a far more flattering silhouette without touching the shoulder seam. Dresses and blouses can similarly be taken in at the side seams to create a closer fit. The caveat is that taking in should be done conservatively — too much and the garment pulls — and some fabrics are easier to work with than others.
Shortening sleeves is an alteration that dramatically improves the look of a jacket or blazer for women with shorter arms, where the standard sleeve length hits below the wrist and covers the hand rather than landing at the correct point. A sleeve shortened by two or three centimetres makes the whole jacket look like it was made to measure.
Replacing buttons is underutilised and highly effective. A good-quality blazer or coat with plastic buttons can be elevated considerably with replacement horn or metal buttons. This is an alteration that costs very little — a tailor can often do the work in thirty minutes — and changes the perceived quality of the garment noticeably.
Alterations That Are Usually Not Worth It
Not every fit problem can be solved by a tailor, and not every alteration makes economic sense relative to the cost and quality of the garment. Letting out at the seams is the most frequently misunderstood category: a garment can only be let out if there is seam allowance to work with, which varies considerably by brand and construction. Fast fashion often has minimal seam allowance, making letting out impractical. Even where the seam allowance exists, letting out can create distortion in the fabric around areas that were cut to fit a smaller size.
Reshaping the shoulders is usually not worth attempting unless the garment is very high quality and the cost of the alteration is proportionate to its value. Shoulder structure is built into the cut and construction of a garment in a way that is complex and expensive to rebuild. A jacket that fits perfectly everywhere except the shoulders is usually better replaced than altered.
Drastically altering the overall size of a garment — going up or down more than one full size — tends to produce results that look altered rather than made to fit. The most successful alterations are the ones that refine and finish a garment that already fits close to correctly, rather than those that attempt a structural transformation.
How to Find a Good Tailor
A good tailor is one of the most valuable working relationships in a wardrobe, and worth taking time to find rather than simply using the nearest available option. Recommendations from people whose clothes look well-fitted are the most reliable source; dry cleaners often offer alteration services but these are not always of the same quality as a dedicated alterations specialist.
When assessing a new tailor, ask to see examples of their work or bring a relatively simple alteration as a first test: a hem, a button replacement, a simple take-in. This provides an opportunity to evaluate the quality of their finishing — the straightness of the hem, the neatness of the stitching, whether the seams press flat without puckering — before entrusting more complex or valuable pieces to them.
Be prepared to travel for quality. A tailor who produces excellent results and is forty minutes away is more useful than a convenient one who produces mediocre work. Alterations are not a frequent requirement — a well-built wardrobe might generate a handful of alteration projects per season — and the quality of the work justifies the extra effort in finding the right person for it.
How to Brief a Tailor
Clear briefing is as important as the choice of tailor. Wear or bring the shoes and any relevant layers you intend to wear with the garment, because hem length in particular depends entirely on footwear. Be specific about what is bothering you: “the waist is too loose” is less useful than “the waist needs to be taken in by approximately two centimetres on each side.” Ask the tailor to mark the adjustment with chalk or pins before you leave so you can confirm it looks correct on the body.
If you are unsure what the problem is — you know something does not look right but cannot identify why — a good tailor will usually diagnose this correctly in a fitting. Describing the garment’s shortcoming (“it looks baggy and unfinished”) and asking for their assessment is a perfectly reasonable approach.
The Pieces That Benefit Most from Tailoring
Investment pieces — the blazer, the trousers, the coat — are the garments where tailoring pays the highest dividends because they are worn most often and their quality is expected to show. A beautifully tailored blazer is among the most versatile pieces in a wardrobe; the same blazer in an untailored fit is significantly less so. Occasion dressing — the dress worn to significant events — justifies alteration because the investment in the piece and the importance of the occasion together make the alteration cost proportionate.
“The distance between looking like you bought a dress and looking like the dress was made for you is often a thirty-pound alteration and one appointment with a skilled tailor.”
Approaching the wardrobe with the understanding that alterations are part of the cost of owning clothes — budgeted for in the same way as cleaning or storage — transforms how you shop and how your clothes look. The garment that fits almost right and sits unworn is less useful than the garment at the same price that has been altered once and is worn constantly. Tailoring is not a luxury reserved for bespoke dressing; it is a practical tool for making a wardrobe work better.
