Is there a three-way mirror?
'Ante' — 'AN-te'. Two syllables. This is the plural of 'anta' (panel). Not the insect 'ant'!
When you want to see 360 degrees — back, front and sides. Three-way mirrors are common in tailoring shops but rarer in fast fashion chains.
'A tre ante' = with three panels. 'Anta' = a hinged panel/flap. 'Specchio a tre ante' is the technical term for a three-way mirror. 'Triplice specchio' is an alternative.
Posso vedere di lato?

Asking for any solution for seeing the back
Può tenermi uno specchio dietro?
Can you hold a mirror behind me?
Asking staff to help with a hand mirror
Tailoring shops ('sartorie') in Italy always have three-way mirrors. High-end boutiques invest in them because seeing the complete 360-degree look is essential to the Italian philosophy of dressing perfectly.
