The Via Montenapoleone outerwear archive: Italian cashmere, leather and the Milan coat you keep for twenty years

The Quadrilatero della Moda is four streets: Via Montenapoleone, Via della Spiga, Via Sant'Andrea and Via Manzoni. You can walk the whole rectangle in twenty minutes if you do not stop, which nobody does. Within it are the houses that invented the modern idea of Italian outerwear, and in the last week of October, when the Milanese collectively decide that it is coat weather, the streets become the best open-air archive of the category anywhere in the world.

The Le Privé styling desk comes to Milan at this time of year on purpose. Not for the shows, which are over by then, but to watch the city dress for real. What you see on Via Montenapoleone at six in the evening in late October is not a trend. It is a set of decisions that Milanese families have been making for generations, about weight and length and the colour of a collar, and it is the most reliable guide to outerwear the desk knows.

The three Milan coats

Every well-dressed wardrobe in this city contains some version of the same three pieces. The first is a long wool or cashmere coat in camel, navy or charcoal, single-breasted, cut to just below the knee. The second is a leather piece: a blouson, a bomber, a short jacket, in black or a dark brown. The third is a knit heavy enough to be worn as a layer on its own in October and under the coat in January. Everything else in the outerwear archive is a variation on these three.

The knit comes first because it is the piece you buy in Milan rather than anywhere else. Loro Piana, on Via Montenapoleone, is the house most members think of when they think of Italian cashmere, and the plain crewneck is the one the desk tells everyone to start with. A navy or a mid-grey, worn directly against the skin or over a fine shirt, under a coat or alone on a mild day. It is the least dramatic thing in this edit and the one that gets worn most.

Leather, and how Milan wears it

Milan's relationship with leather is older and more relaxed than London's or Paris's. Here a leather jacket is not a statement. It is what you wear on a Saturday to walk from Brera to the Navigli, over a knit, with tailored trousers and a good shoe. The shape has changed over the years. The fitted biker of the nineties gave way to the boxier blouson, and in the last few seasons the flight jacket, with its rounded shoulder and ribbed hem, has taken over the Quadrilatero.

Balenciaga's flight jacket is the version the styling desk recommends because the proportion is generous without being costume. It layers over the Loro Piana crewneck without pulling at the shoulder, and it looks right with everything from a wide trouser to a short skirt and a tall boot. In black leather it will outlast most of the coats bought around it.

A Milan coat is a twenty-year decision. Buy the plainest version of the best one, and let the city teach you how to wear it.

The walk: Montenapoleone to Via della Spiga

Start at the Via Manzoni end of Via Montenapoleone and walk south. Loro Piana, Bottega Veneta, Prada, Saint Laurent and Balenciaga are all on the street or a few metres off it, and the windows at this time of year are the outerwear archive in miniature. At the Corso Matteotti end, turn left on Via Sant'Andrea and then left again onto Via della Spiga, which is pedestrian, quieter and where the smaller boutiques are. The Four Seasons on Via Gesù sits in the middle of the rectangle, in a former convent, and is where the desk tends to base itself for a Milan trip for exactly that reason.

Finish on Via della Spiga at the Via Manzoni end and walk the few minutes to Brera for an aperitivo. Bar Brera on Via Brera and the courtyard at the Pinacoteca are the usual stops. The coat, by this point, is doing all the work.

The trench, the camel coat and what to leave out

Members often ask about the leather trench. It is a beautiful object and the Milanese houses make the best ones, but it is a third or fourth coat, not a first. The same is true of the long shearling and the quilted puffer, which has its place at altitude and much less of one on Via Montenapoleone. Build the three core pieces first, then add.

The camel coat is the exception. If you already own a navy or charcoal overcoat from London, the Milan purchase is the camel, because nobody cuts it better than the Italian houses and because it is the one colour that changes an entire wardrobe. Wear it with black, with grey, with denim, with the crewneck underneath. Carry something dark and soft with it: Bottega Veneta's Andiamo in black is the bag the desk pairs with camel most often, because the weave gives the plainest coat a texture to answer.

Shipping it home

Milan is a city where members buy heavy things, and the Milan Farfetch partner boutique can ship a coat home so that it arrives before you do. The Le Prive Network concierge keeps the boutique contacts, the alteration tailor near Via Sant'Andrea that our members use and the Brera addresses in one place. Follow the season on leprive.net and at @leprive.network, and come in late October. The city will show you the rest.
