Three sweaters, each made for its own part of a man's day.
One goes under a jacket and asks nothing of it. One stands in for a shirt and a tie. One changes its mind between the morning and the evening. All three are knitted at twelve gauge, fully fashioned and linked by hand, in the house's cashmere or its extrafine merino, and each is shaped for the thing it is asked to do, above a lapel or a coat collar or across a table. What follows is each of the three, and what each one is for.
A band of four centimetres in two-by-two rib, knitted as its own piece and linked to the body. Two-by-two is two stitches raised and two sunk, repeating; it draws in across the width and returns, and that return is what holds the neck round through years of being pulled over a head. Four centimetres is the height at which the band stands without standing away from the neck. Under a jacket it clears the lapel, and a shirt collar sits over it or under it. On its own it is the plainest of the three, which is most of why it is the one that gets worn.
A tube of thirty-six centimetres, folded once, so eighteen stand at the neck. Folded, there are two thicknesses of cloth at the throat and a knitted fold at the top rather than an edge. Thirty-six centimetres at twelve gauge is the heaviest part of the garment, and it hangs where the body carries nothing, so the rest of the piece is proportioned to hold it up; that is why the fold is still standing in February. Under a jacket it stands in for a shirt and a tie, and it wants a lapel with some room in it. On its own it closes the throat and will carry a coat through January.
A standing collar of eight centimetres, and a brass zip of twenty running in a placket of three. The zip is the one part of the garment that is not knitted. It runs in a placket of its own rather than against the knit, so the stitches either side of it are not asked to stretch with it, and it is brass because it is also the one part that can be repaired. Twenty centimetres opens to the breastbone and stops. Eight centimetres stands when the zip is closed and folds over when it is open: a shirt at the throat one way, a roll neck the other, and the only one of the three you can change after you have left the house.
The three are cut to one set of measurements at the shoulder, the armhole and the sleeve, and finished in the same two-by-two rib at the cuff and the hem. Two things follow from that. Your size is your size in all three, so a man who has one of them does not have to think about it again. And two of them together read as one wardrobe rather than two purchases, because the shoulders sit the same way under the same jacket and the cuffs end at the same place on the same wrist.
The Girocollo, if there is going to be one. It goes under what is already in the wardrobe and asks nothing of it. The Dolcevita changes what you can leave at home, which is a shirt and a tie, and that is worth the first winter you travel with it. La Mezza Zip is for a day with two halves to it. There is no wrong order to meet them in; there is an order in which each one adds something the last could not do, and this is it.
