A peacoat is hip length, double breasted and cut from heavy melton wool; an overcoat reaches the knee or below in finer cloth and is made to cover a suit; a trench is belted, water resistant and lighter than either.
All three are dark wool coats in most people’s wardrobes, which is why they blur together. Length is the fastest way to tell them apart from across a street.

|---|---|---|---|
| Length | Hip | Knee or below | Knee |
| Closure | Double breasted, broad lapel | Single or double | Double breasted, belted |
| Cloth | Heavy melton wool | Finer wool or cashmere | Cotton gabardine |
| Covers a suit jacket | No | Yes | Yes |
| Weather | Cold and wind | Cold, formal | Rain, mild cold |
How to tell them apart in a photo
If it stops at the hip, it is a peacoat. If it has a belt and a flap across one shoulder, it is a trench. Everything else long and plain is an overcoat.

Questions people actually ask
Can a peacoat be worn over a suit?
It stops too short and leaves the suit jacket hanging below it. For tailoring you want an overcoat.
Why is it called a peacoat?
Most likely from the Dutch word pij, a coarse heavy wool used for sailors’ jackets. A competing story derives it from a naval abbreviation for pilot cloth. Both point at the same thing: the coat is named after the fabric it was cut from.
Is a topcoat just a shorter overcoat?
No, it is a lighter one. Topcoat cloth runs thinner so the coat works in mild weather over a jacket without cooking you. Lengths overlap heavily. If a shop is using the words carefully, topcoat tells you about season and overcoat tells you about depth of winter.
What is melton wool?
Densely woven wool that has been fulled and cropped until the surface is smooth and the weave disappears. It blocks wind, holds shape without lining help and does not fray, so it can be cut with raw edges. Peacoats use it because sailors needed all of that.
