The Voice is kinda like a Nordstram Rack, but with high end Italian shit. We even "talked them down" on a Corneliani blazer for my dad. Went from 340 euro to 290 euro. Retail was over 600. Also, this pace was dead. Not sure why as it was awesome. It was a random weekday at mid-morning, but we were there two hours and were probably the only customers.
Also hit up the Castelo Romano outlets south of Rome about 25k.
Nice stores, outdoor style place similar to US outlet malls, but with awesome brands (Loro Piana, Zenga, Ferragmo, Valentino, Etro, etc, also Boss, Boggi, etc. )
Mostly "normal" outlet prices, i.e. 30-70% off (still mostly too damn rich for my blood).
Didn't know this until after I left, but you can show your Rome boarding pass from the flight and get 20% more off at Romano.
Also, FYI, 155 euro is the minimum purchase to get the VAT refund.
I did luck out and found my wife an insanely awesome Loro Piana blazer (1,500 euro retail) for 120 euros!
LP wool stuff is just over the top, unless you are a millionaire. 400 euro scarves, oulet price!
