Yes, an ill-fitting suit can be altered. Most standard adjustments can be handled by professional tailors. Here are the details regarding feasibility and important considerations:
Standard areas that can be altered
Sleeve length/Jacket length:These are the easiest to adjust. Sleeve length can be modified at either the cuff or the sleeve head. It is recommended to limit jacket length adjustments to within 4 cm to avoid disrupting the visual balance between the pockets and the hem.
Waist/Chest/Sleeve width: Provided there is sufficient seam allowance, these areas can be taken in or slightly let out; adjustments within a 4 cm range generally have minimal impact on the suit's overall cut.
Shoulder width: Adjustments of less than 1 cm have little impact on other areas. However, changes exceeding 1.5 cm require corresponding adjustments to the armhole and sleeve width to prevent the suit's proportions from becoming distorted.
Prerequisites and limitations
It is preferable to "buy large and alter down" (taking a larger size in); making a suit smaller is far easier than making it larger, as the latter requires sufficient seam allowance in the fabric.
Major structural issues-such as a collar that does not sit flush against the neck or significant horizontal creasing across the back-are extremely difficult to fix and usually beyond the capability of an average tailor.
Altering high-end suits constructed with full-canvas interfacing involves complex procedures; it is advisable to use a professional tailoring service to avoid damaging the original construction.
