Quick Answer: Three repairs cover the overwhelming majority of what actually retires clothing: a dropped hem, a lost button, and a stuck or split zip. All three are learnable in an afternoon with a needle, matching thread, and about fifteen minutes each. What to pay for instead: anything structural (shoulders, linings, seat seams), knitwear reweaving, and leather. The rule that decides it: if the repair is on a visible seam under tension, use a professional; if it is a fastening or a hem, do it yourself.

Repair 1: The dropped hem

This is the single most common garment failure and the easiest to fix. A hem drops when the original blind stitching breaks at one point and then unravels progressively along the fold.

Catch it early, at the first inch. A small drop is a five minute repair; a hem that has unravelled halfway around needs the whole thing redoing.

Use a slip stitch, not a running stitch. You want to catch a single thread of the outer fabric and a good bite of the folded edge - which is what makes the stitching invisible from the front.

Match the thread to the fabric, not to the eye. In doubt, go one shade darker rather than lighter, since darker thread disappears and lighter thread announces itself.

Do not pull the stitches tight. A hem stitched under tension puckers, and puckering is far more visible than the original problem was.

Hemming tape is a genuine temporary fix and a poor permanent one. It works for an evening, and over time it stiffens the hem and can leave a mark that dry cleaning will not remove.

And press it afterwards. A pressed hem looks professional and an unpressed one looks mended, and that is most of the visible difference between the two.

Repair 2: The lost button

Sewing a button on is easy; sewing one on so it stays is slightly less so - and the difference is in two details most people skip.

Use a shank. Place a pin or a matchstick across the top of the button while you stitch, then remove it and wind the thread around the loose threads underneath. This creates the gap the buttonhole fabric needs to sit in, and it is why factory buttons sit properly and hand-sewn ones sometimes do not.

Do not overfill the holes. Six passes is plenty. More thread makes the button sit rigid, and it puts strain on the fabric rather than on the thread.

Finish underneath, not on top. A knot on the reverse under the button is invisible and does not abrade against the fabric each time the garment is worn.

Check the spare button first. Most garments ship with one in a small bag or stitched inside the side seam, and it will be an exact match in a way a shop button will not.

Replace the whole set if you cannot match it. Mismatched buttons read as a repair; a full replacement set reads as a design choice, and it costs very little.

And check the neighbouring buttons. One button coming off usually means the others were sewn at the same time with the same thread, and they are next.

Repair 3: The stuck or split zip

Most zip failures are not broken zips at all. A zip that splits open behind the slider almost always means the slider has worn slightly wide, and the teeth are no longer being pressed together.

Try the pliers fix first, gently. Squeeze the sides of the slider very slightly with pliers, a fraction at a time, then test. This resolves a large proportion of split zips outright.

For a stuck zip, lubricate rather than force. A graphite pencil rubbed along the teeth, or a candle end, frees most jams without any risk to the fabric.

Check for caught fabric or thread before anything else. A lining thread caught in the slider is the most common cause of a jam, and forcing it makes it considerably worse.

Replace a slider rather than a whole zip where you can. Slider replacement is markedly cheaper than a full zip replacement and is often all that is needed.

But pay for a zip in a fitted dress or a leather item. Those are set into seams under tension or into material you cannot re-pierce, which puts them firmly in the professional category.

And never force a zip on a garment you care about. The teeth themselves are the part that cannot be repaired once damaged.

What should you always pay for?

Anything structural. Shoulders, armholes, and the seat seam of trousers are under load and shaped in three dimensions, and a home repair here shows immediately.

Knitwear holes need reweaving, not stitching. A stitched knit hole puckers and spreads; proper reweaving reconstructs the loops and is close to invisible on good pieces.

Leather and suede, without exception. Every needle hole is permanent, and there is no practice run available on a jacket you own.

Relining a coat. It is fiddly, three-dimensional, and transforms a garment when done properly - one of the best-value professional repairs there is.

Anything on a garment you would be upset to lose. The real calculation is regret, not money: the cost of the repair against the cost of ruining the piece while learning.

And invisible mending on tailoring. A skilled repair on a wool jacket genuinely disappears, and it is not something achievable at a kitchen table.

Find a local alterations shop and use it repeatedly. They get to know your garments and your fit, and the relationship is worth considerably more than the individual repairs.

FAQ: Clothing Repairs, Answered

What repairs should I learn to do myself?

Dropped hems, buttons, and simple zip slider fixes. Together they account for most of what actually takes clothes out of rotation, and each takes about fifteen minutes.

How do I sew a button so it stays on?

Use a shank - hold a pin across the top of the button while stitching, then wind the thread underneath to create a gap. Six passes through the holes, and knot on the reverse.

Can a split zip be fixed without replacing it?

Usually yes. A split behind the slider means the slider has worn wide - squeeze its sides very gently with pliers, a fraction at a time, and test.

Is hemming tape a real solution?

As a temporary fix for one evening, yes. Permanently it stiffens the hem and can leave a mark that dry cleaning will not remove.

What should I never attempt at home?

Shoulders, armholes, seat seams, knitwear holes, leather, and relining. Structural seams and unforgiving materials both punish practice.

How do I match thread?

Hold candidates against the fabric in daylight, and if in doubt go one shade darker. Darker thread disappears; lighter thread announces itself.

Is it worth paying to repair cheap clothing?

Rarely for structural work, often for a button or a hem you do yourself. The calculation changes entirely once the repair costs nothing but fifteen minutes.

TL;DR:

• Three repairs cover most garment deaths: dropped hem, lost button, stuck or split zip.
• Hems: slip stitch, catching a single thread of the outer fabric. Do not pull tight, and press afterwards.
• Buttons: use a shank. Pin across the top while stitching, wind thread underneath, six passes, knot on the reverse.
• Zips: most are not broken. Squeeze the slider gently with pliers for splits; graphite or candle wax for jams.
• Check the spare button sewn inside the side seam before buying a replacement.
• Always pay for: shoulders, armholes, seat seams, knitwear reweaving, leather, and relining.
• The rule: fastenings and hems yourself; visible seams under tension to a professional.
• Find one local alterations shop and use it repeatedly. The relationship outvalues the individual jobs.
