aiguilleter

Aiguilleter is a rare, archaic verb meaning to fasten or lace something with an aiguillette — the small metal-tipped cord once used to attach hose to a doublet in old French dress. It has essentially disappeared from modern usage outside historical or costume contexts.

• Le valet aiguilletait les chausses de son maître chaque matin. — The valet laced up his master's hose every morning.
• Dans les costumes d'époque, on aiguillette encore les pièces à l'ancienne. — In period costumes, pieces are still laced up the old-fashioned way.
• Ce terme, aiguilleter, ne survit guère que chez les historiens du costume. — This term, aiguilleter, survives mainly among costume historians.

This verb is so rare that learners are unlikely to ever need it — if you mean simply 'to lace up' in modern French, use lacer instead.
