How to Fix a Loose Button: Shank, Thread, Not Glue
Glue fails the second time you sit. A needle, matching thread, and a shank so the button can stand off the cloth. Five minutes. A $4 tin of extra buttons is the real kit.

Why glue is a delay
Cyanoacrylate sits on the face, stains, and shears off the first hard pull. Thread is a flexible hinge. If the cloth around the buttonhole is shredded, you need a patch or a tailor ($10–20), not a bigger blob.
The shank is the part people skip
A button sewn flat cannot clear a thick placket. The wrap between button and cloth is the shank. Shirt buttons need a short one; coat buttons need a longer one. That is the whole trick. Use a toothpick as a spacer on jackets, pull it out, wrap the gap.
- Doubled thread, knot the end
- Four to six passes per pair of holes
- Wrap the stem, then knot on the back
Keep the spare
The extra button in the placket hem is not a souvenir. Cut it off only when you need it, and sew the remaining spares into a tin. A $6 sewing kit in a desk drawer ends the emergency better than a safety pin on a job interview.
Questions, answered
- Dental floss as thread?
- Waxed floss is strong and ugly. Use it on a coat in a hotel. Use real thread on a white oxford.
- How tight?
- Firm enough that the button does not spin like a wheel, loose enough that the placket still slides under it. The shank gives you that gap.
- The button cracked.
- Replace it. A mismatched spare is better than a glued half. Mother-of-pearl shirt buttons are a few dollars a card at a notion shop.
