Most off-the-rack suits need alterations. Even excellent ones. The question is not whether to alter, but what to alter, in what order, and to what degree. This guide covers what's worth doing, what to approach with caution, and what's usually a waste of money.
Alterations Worth Doing on Almost Every Suit
Three alterations transform almost any suit and are nearly always worth the cost. Trouser hemming is the most fundamental — trousers should sit on your actual shoes with the break you prefer, not at whatever length the maker happened to choose. Cost: $25-45. Time: 7-10 business days standard, often available same-day. There's no good reason to ever wear unhemmed or improperly hemmed trousers.
Waist suppression on the jacket is the highest-value alteration in tailoring. A subtle narrowing at the waist — typically one to two inches of suppression at the side seams — transforms how a suit looks more than almost anything else. Most ready-to-wear is cut conservatively at the waist and benefits significantly from this work. Cost: $80-140.
Sleeve length matters more than most clients realize. Jacket sleeves should end half an inch above the shirt cuff. If yours don't, fix it. From the cuff (for standard suits) costs $45-75; from the shoulder (for high-end suits with working buttonholes) costs $125-185.
Alterations Worth Doing on Most Suits
Trouser tapering — narrowing the trouser from the knee down to the ankle — is often worth doing on modern suits where the trouser is cut wider than current proportions favor. Cost: $55-95. Be careful not to taper too aggressively; the trouser should still have enough room to break properly over the shoe.
Jacket length adjustment is worth doing when the suit is meaningfully off — typically when the jacket is too long, hiding the seat (a sign of older or larger sizing). Shortening more than an inch and a half affects the visual proportions of the jacket and front quarters and should be done by a tailor who understands the consequences. Cost: $145-225.
Collar adjustment on the jacket — fixing a collar gap (where the jacket collar doesn't sit flush against the shirt collar) — is one of the more complex alterations but often essential for a polished look. It requires reshaping the upper back and rebalancing the jacket. Cost: $185-285.
Alterations to Approach with Caution
Shoulder adjustments are technically possible but rarely worth the cost. The shoulder is the structural foundation of the jacket — pad, canvas, sleeve attachment, and collar all reference the shoulder. Adjusting it requires disassembling and rebuilding all four. On a $500 suit, it makes no sense. On a $5,000 suit, an expert can do it but charges $300-500. Better path: don't buy a suit with the wrong shoulder fit.
Letting out a suit is limited by the seam allowance the maker left. Traditional Italian and English bespoke suits have generous seam allowances and can be let out an inch or more. Fast-fashion suits often have almost no seam allowance and can be let out maybe a quarter inch before the seams run out. Before buying a suit, look inside at the seams to see what's available.
Major resizing — taking a 44R down to a 42R, for example — is achievable but requires careful work on every panel of the jacket and trouser. Cost: $250-450 depending on construction. Usually worth doing only on high-end suits or those with sentimental value.
Alterations Usually Not Worth Doing
Rebuilding a lining in an inexpensive suit doesn't make economic sense — the cost of the work approaches the cost of the suit. On a luxury suit it's worthwhile. On a $400 suit, replace the suit.
Repairing a damaged shoulder on a suit that doesn't otherwise warrant the investment — better to retire the suit than to spend $400 on a shoulder repair on a $600 suit.
Aggressive tapering to chase a trend that may change in eighteen months — alterations should follow your body, not your Instagram feed. Subtle adjustments age well; extreme ones look dated quickly.
What to Tell Your Tailor
Bring the shoes you'll actually wear with the suit. Trouser break is meaningless without the right shoes; jacket length references the shoe height. Bring the shirt and tie you'll wear — jacket fit changes with what's underneath. Stand naturally during the fitting — don't suck in your stomach, don't square your shoulders. The tailor needs to see how you actually stand.
Explain how you'll wear the suit. Conference rooms and weddings ask different things. A suit altered for daily wear has different priorities (mobility, durability) than one altered for a single event (visual perfection in photos).
Ask before you commit to anything. A good tailor will tell you honestly what's worth doing, what isn't, and what the trade-offs are. If the tailor recommends $800 of alterations on a $500 suit, find a different tailor.
The Cost of Alterations
For a typical off-the-rack suit needing standard alterations, expect $200-450 in tailoring on top of the suit's purchase price. For high-end suits requiring shoulder-based sleeve work, working-buttonhole preservation, or complex resizing, $400-800 is realistic. Plan for it. A $1,500 suit altered to fit properly is significantly better-looking than a $2,500 suit altered poorly or not at all.
Standard turnaround for most alterations is seven to ten business days. Rush service (24-48 hours) is available for an additional fee. Plan ahead for events; bring the suit in at least three weeks before the date.
