Suit Alterations
Modifications made to a finished suit to improve fit. Alterations range from simple (hemming trousers) to complex (adjusting shoulders), and understanding what is possible helps set realistic client expectations.
Suit alterations are modifications made to a finished garment to improve its fit on the wearer. While a bespoke or made-to-measure suit is built to fit from the start, even these garments may require fine-tuning after the initial delivery. For off-the-rack suits, alterations are almost always necessary to achieve an acceptable fit. Understanding which alterations are straightforward, which are difficult, and which are inadvisable is essential knowledge for both tailors and their clients. The general rule is that it is easier and cheaper to take a garment in than to let it out, and structural alterations (shoulders, chest balance) are far more complex than peripheral ones (sleeves, hems).
Simple Alterations
Simple alterations are quick, relatively inexpensive, and carry minimal risk. They include hemming trouser legs (adjusting the length), tapering trouser legs (slimming the leg below the knee), taking in or letting out the trouser waist (usually possible by 1 to 2 inches in either direction), shortening jacket sleeves (from the cuff end), and adjusting the jacket body at the side seams (taking in for a slimmer fit). These alterations can typically be completed in a few days and cost between $15 and $75 each. They should be considered standard practice when purchasing any off-the-rack suit.
Moderate Alterations
Moderate alterations require more skill and time and are correspondingly more expensive. These include shortening the jacket from the bottom hem, adjusting the collar to eliminate gapping, reworking the back of the jacket to remove excess fabric or smooth wrinkles, relocating buttons and reworking the button stance, adjusting sleeve pitch to correct twisting, and letting out or taking in the jacket chest. These alterations typically cost $50 to $200 each and may require one or two fittings. They should be performed by an experienced alterations tailor who understands suit construction.
Complex Alterations
Complex alterations involve restructuring significant portions of the jacket and should only be attempted by highly skilled tailors. The most notable is adjusting the shoulders, which requires detaching the sleeves, altering the shoulder pads, reshaping the shoulder seam, and re-setting the sleeves. Shortening sleeves from the shoulder (necessary when functional buttonholes prevent cuff-end shortening) is similarly involved. Adjusting the chest balance (changing the relationship between front and back to correct posture-related fit issues) is another complex alteration. These modifications can cost $200 to $500 or more and may require multiple fittings. In some cases, the cost of a complex alteration approaches the price of a new garment.
What Cannot Be Altered
Some fit issues are effectively impossible to correct through alteration. Making a jacket significantly larger is limited by the seam allowances (usually only 0.5 to 1 inch is available to let out). Changing the overall shoulder width by more than half an inch in either direction is impractical. Altering the armhole size is extremely difficult because it involves restructuring the entire side panel, sleeve, and chest area. Changing a fused jacket to canvas construction cannot be done. If a jacket has fundamental structural issues, whether the shoulders are dramatically wrong or the armholes are too low, it is generally better to start over than to attempt heroic alterations.
Pro Tip
When a client brings in a suit for alterations, start by checking the shoulders. If the shoulders fit, almost everything else can be adjusted. If the shoulders are wrong, have an honest conversation about whether the suit is worth altering or whether the client would be better served by a garment that fits the shoulders correctly from the start.
How Sartorly Helps
Sartorly helps tailors reduce alteration needs by getting the fit right from the start. When clients can visualize themselves in a suit before it is made, they provide better feedback during the design stage, which translates directly to fewer post-delivery alterations and happier outcomes.

Common Questions About Suit Alterations
Basic alterations (trouser hem, waist adjustment, sleeve length) typically cost $50 to $150 total. More extensive work (jacket body, collar, sleeve pitch) can add $100 to $300. A full suite of alterations on an off-the-rack suit might run $200 to $400. If alterations will cost more than 30 to 40 percent of the suit's purchase price, consider a better-fitting suit or made-to-measure instead.
Slightly too large. It is much easier and more successful to take a garment in than to let it out. A jacket that is slightly large through the chest and body can be taken in at the side seams. A jacket that is too small cannot effectively be enlarged, especially in the shoulders and chest.
Not from the cuff end, because the functional buttonholes cannot be moved. Surgeon's cuff sleeves must be shortened from the shoulder, which is a complex and expensive alteration. This is why many tailors advise against functional buttonholes on off-the-rack suits or suits that may need future sleeve adjustments.
