How do I measure my hat size?

Wrap a soft tape around your head about half an inch above the ears and across the mid-forehead, where the hat will actually sit. That circumference in inches or centimeters is your size; most brands publish a size chart that maps it. Measure twice — hair and the season change the number slightly.

Fedora, trilby, or bucket?

The fedora has a taller crown and a wider brim and reads more formal; the trilby is its narrower cousin and reads more casual; the bucket is soft, packable, and level 1. For most city scenes at level 2, the trilby or the bucket is the safer call — the fedora is a commitment.

When do I take a hat off?

Indoors, generally — restaurants, homes, offices. Exceptions exist (a hotel lobby, a barn, a hat that's part of a uniform), but the default in most Western settings is that hats come off inside. Outdoors, the hat stays on, including at a table on a terrace.

The hat guide: crown, brim, and the scene it belongs to

A hat is the accessory that changes a scene the most and forgives the least. Crown height, brim width, and material decide whether the same head reads city, country, or costume — and there’s very little middle ground.

The three dimensions

1. Crown height. A taller crown reads more formal and more vintage; a shorter, tapered crown reads modern and casual. The fedora sits at the formal end, the trilby in the middle, the bucket and the beanie at the casual end. Match the crown to the scene’s formality, not to your face shape first.

2. Brim width. A wider brim shades more and reads more deliberate; a narrow brim is easier to wear and less likely to collide with a collar or a shoulder. For a first felt hat, a brim around 2 to 2.5 inches is the versatile range — wide enough to read as a hat, narrow enough to wear on a train.

3. Material and season. Felt (wool or fur) for autumn and winter; straw and cotton for summer; knit for cold. A wool felt hat in July reads wrong no matter how good the shape is, and a straw hat in December reads like a costume.

Getting the fit right

Measure the circumference of your head where the hat will sit — about half an inch above the ears, across the mid-forehead. Most brands publish a size chart mapping that number. A hat should sit snugly enough that a gust doesn’t take it and loosely enough that it doesn’t leave a mark after an hour.

Check the interior: a sweatband in leather or cotton is a sign of a hat built to be worn; a bare synthetic band is a sign of a hat built to be sold.

How it reads in a scene

Level 1: a beanie, a bucket, a cap. Level 2: a trilby or a felt bucket with a structured crown. Level 3: a fedora in a neutral felt, if the rest of the outfit is quiet enough to support it. Above level 3, hats are a statement and usually stay at the door.

Brim, height, and proportion

Read the brim against your shoulders, not your face. A brim that ends inside the shoulder line keeps the hat inside the outfit; one that extends past it makes the hat the subject. Height does the same work vertically: a tall crown adds presence, which suits a long neck and overwhelms a short one. The practical test is the silhouette at ten feet, not the mirror at one. If the hat is the first thing anyone notices, it is either the right hat for a level 3 evening or the wrong hat for a Tuesday.

Storage matters as much as shape. Rest a felt hat on its crown, never its brim, and steam a dent out over a kettle rather than pressing it flat.

The rule that matters: one hat, one scene, and it comes off indoors. Everything else is shape and shade.
