What to wear to a fall wedding when the reception is outside

Fall weddings drop 20 degrees between the ceremony and the toasts. Here is the suit, the layer and the shoes that handle both ends of that.

The ceremony starts at 4. The sun is gone by 6:40. By the time anyone stands up to give a toast you're on grass in the dark at 48 degrees, and the guy who dressed for the ceremony photos is the one wearing a borrowed blanket like a shawl.

Fall weddings are the best ones to attend and the easiest ones to underdress for. Summer is a heat problem, and we covered that in the summer wedding guide. Fall is a range problem. One outfit has to work at 72 in the sun and 45 after dark, and that is a fabric decision more than a style decision.

Read the venue before the dress code

The invite gives you two or three words. "Cocktail attire," maybe "semi formal," often nothing at all. The venue tells you more than any of them.

Barn, vineyard, orchard, tented field: you are outside for most of the night, standing on ground that is damp by 9pm no matter what the forecast said at noon. Hotel ballroom, restaurant, city loft: heated, indoors, one suit weight covers the whole evening.

Look the venue up on Maps and click through the photos. Two minutes and you know whether the reception sits under a tent. If it does, treat it as outdoors. Patio heaters warm the six feet of air around them and nothing past that.

Dress code translation, short version. Cocktail attire in October means a suit and a tie you can lose after dinner. Semi formal means the same thing in a darker suit. Black tie optional means wear a dark suit if you don't own a tux and nobody will count. An invite that says nothing means a suit.

Go darker and heavier than you did in June

Two things change from summer. The color drops and the weight goes up.

Charcoal and navy work at every wedding in every season, which is why they are the boring correct answer. Fall hands you two more: brown and deep green. A tobacco or chocolate brown suit at an October wedding looks like a decision rather than a default, and it photographs warmer than black against fall light. Black suits belong at funerals and black tie, not here.

Leave the linen, the seersucker, the tan cotton and the light grey at home. All fine in July, all thin looking in a November photo.

Weight is the part most guys skip. Standard worsted wool runs 9 to 11 ounces and carries most of the year. Wool flannel runs 12 to 14, holds a little surface texture, and is noticeably warmer without reading heavy. Tweed is warmer again, though it tips into costume fast if everything else in the outfit is not quiet.

Suitsupply sits at $400 to $600 and fits a lot of guys straight off the rack. J.Crew's Ludlow lands near $400 and drops to $250 on sale a few times a year. Spier and Mackay does half canvassed suits around $350. If you get one wedding invite a year, renting from The Black Tux or Generation Tux runs $150 to $200 and skips the closet space entirely.

Whatever you buy, add $50 to $80 for a tailor. Sleeve length and trouser hem are the two that show up in every single photo, and the tailoring guide has the rest of the price list.

The layer that saves the last two hours

Warmth has to live somewhere other than a coat you will be carrying all night. Two options, and they stack.

A fine gauge merino crewneck under the jacket is the move almost nobody tries. Shirt, tie, thin sweater over both, jacket on top. Real warmth, almost no bulk, and the tie showing above the neckline looks intentional. Uniqlo's extra fine merino is $40 and comes in the right colors for this: charcoal, dark green, burgundy. Chunky knits do not work under a jacket. They bunch at the armhole and you will feel it inside an hour.

Then a coat for the walks between buildings. A topcoat in navy, charcoal or camel, hitting mid thigh or lower. The one rule: it has to be longer than your suit jacket, or the jacket hem pokes out underneath and the whole thing reads borrowed. Uniqlo's wool blend is about $150, J.Crew's about $300, and a thrifted wool overcoat is $40 if you are patient. A puffer over a suit is a compromise everyone can see, but a warm guy in a puffer still beats a shivering guy in a jacket.

The ground is wet, so dress for it

Leather soles on damp grass are slick and they stain. Save those for the ballroom.

Dark brown leather derby shoes with thick rubber lug soles and dark over the calf socks, worn with charcoal wool flannel trousers on damp grass covered in wet fallen leaves.

Outdoors, wear something with a rubber sole: a dark brown derby, a black cap toe on a Dainite sole, a brown suede chelsea. A boot under a suit trouser looks right in fall, and you will be the only guest not walking across the lawn on his heels. We went through which pairs earn their place in the shoes guide.

Socks over the calf, dark, matched to the trouser instead of the shoe. No show socks are a summer thing, and there is a specific moment where you sit down, cross your legs, and everybody learns which kind you wore.

Default outfit if you would rather not think about any of this:

Charcoal or navy wool suit, flannel if you have the option
White or light blue shirt, spread or semi spread collar
Knit or wool tie, one shade darker than the suit
Thin merino crewneck in the bag, on by 8pm
Brown rubber soled derby or chelsea, dark over the calf socks

Call it $500 to $700 new, less if you rent the suit or catch a sale, and it covers every fall wedding you get invited to for the next five years.

Check the forecast for 9pm, not for 4pm. That is the number you are dressing for.
