I'm just looking, thank you.
The double 'd' in 'guardando' is held a beat longer than a single 'd'. Say 'guar-DAN-do'.
When a shop assistant approaches and you're not ready to ask for help. Polite way to browse freely without being rude.
'Sto + gerundio' (guardando) forms the present progressive in Italian, equivalent to 'I am looking'. Adding 'solo' (only/just) softens the refusal politely.
Do solo un'occhiata.
I'm just having a look.
More colloquial, common among younger shoppers
Per ora guardo, grazie.
For now I'm just looking, thanks.
Implies you might ask for help later
Grazie, mi guardo in giro.
Thanks, I'll look around.
Most casual variant
Always greet with 'Buongiorno' or 'Buonasera' before saying anything else in an Italian shop — walking in silently and ignoring staff is considered impolite.
