Description
Give your shirt a little breathing room without reaching for a new one. These white 12mm plastic collar extenders from Giddy Square sit between your shirt’s top button and buttonhole, creating a fixed extra gap of up to half a size.
They’re designed to look neat and stay hidden — the white button head blends with most white shirt buttons, and the low profile sits discreetly beneath a tie or bow tie. Ideal for dress shirts, office wear, suits and uniforms.
How to fit
- Slide the extender loop over your collar button
- Pass the extender’s button through your shirt’s normal buttonhole
- Done — fasten as usual
Pack of 3 — keep one in your jacket pocket for emergencies, use the others at home and at the office.
Best suited to standard shirt buttonholes. Not designed for thick denim or waistband buttons. Check your buttonhole width before use.
