The argument against buying standard sizing and altering it is not that alteration fails. It is that alteration has a budget, and the garments that need the most of it are the ones least able to absorb it.
Worth paying for
- Trouser and skirt hems. The cheapest alteration available and frequently the difference between a garment being worn and being stored.
- Sleeve length on an unlined jacket. Straightforward, and it restores the whole cuff-to-hand proportion.
- Waist suppression on a trouser that fits at the hip. A common petite mismatch and an easy fix.
Rarely worth it
- Shoulders on a structured jacket. The most expensive alteration in tailoring, and the result is usually a compromise.Footnote 1
- Rise on a trouser. Reconstructing a rise changes the pocket bags, the fly and the waistband simultaneously.
- Shortening a lined coat from the hem when the pockets, plackets and button spacing were drafted for the original length.
Pay for length. Do not pay for architecture.
A reasonable rule: if the alteration only moves an edge, it is probably worth it. If it moves a seam that other seams depend on, buy something else.
