If you stop by Two Sizes in Rome, expect a small, design-focused boutique rather than a large store: stock is limited, items tend to be Italian-made, and sizes can run tighter than you expect, so try things on before you buy. The staff usually speak some English and can help with fit; they take cards but bring a bit of cash for very small purchases or if the card machine is down. Hours are often midday to early evening with a possible lunch break, and you can pop in between sightseeing since it’s in the historic center—no reservation needed, but give yourself time during late afternoon when it gets busiest.
