Visiting Fashion Outlets in Tuscany
Hello Roberto and Welcome to the Forum!!
Tuscany is indeed the right place for fashion outlets!
I'm happy to help you.
Tuscany is rather a large region, the major and fastest trains running from Rome arrive to Florence's Santa Maria Novella train station, the main station in the city. You might have a look at some useful information on how to get to Tuscany by train at this link:

As for the fashion outlets, there are actually a lot of them in Tuscany, especially in the area around Florence; but I would surely suggest two fashion outlets that are worth visiting since they feature a lot of shops together and the best brands, the first is the McArthurGlenn Barberino Outlet, north of Florence, easily accessible with a shuttle service from Florence Santa Maria Novella train Station.
Another very good one is The Mall in Reggello, again near Florence, with other many famous brands. It can be easily reached both by bus or train, still from Florence's SMN train station.
You can find all info here:

One last fashion outlet I'd recommend is the Valchiana Outlet Village located near Arezzo, that you can reach by bus from Arezzo's train station:

The Barberino Outlet and the Mall are near each other, so it will take just a short journey from one outlet to the other, the Valchiana Oulet Village is a bit further, you have to take a train from Florence to Arezzo, but it's a short time anyway.
If you need some more suggestions or help please contact me again
Enjoy your outlet tours!
