Buying a belt: how to choose the right belt for every outfit

Buying a belt seems simple, until you have to choose between leather, canvas, stretch, different buckles and sizes. A belt that looks right in a photo may turn out to be too short, fail to fit through your belt loops or quickly lose its shape. Well-known brand names don’t automatically tell you anything about fit or care either.

So, keep an eye out for these three common pitfalls:

• Choosing the wrong size: a size 80 or 90 doesn’t refer to your waist measurement in exactly the same way across every brand. Always check the size guide and measure your waist or a belt that fits you well.
• Confusing materials: “leather-look”, bonded leather fibre, cotton blends and genuine leather are different materials, each with its own look and care requirements.
• Choosing a buckle that doesn’t suit your clothes: a wide, eye-catching buckle can be awkward with a suit, while a slim, formal belt may look out of place with jeans.

What should you look for before buying a belt?

1. Choose the right size and length

An adjustable belt gives you more flexibility, but the stated size still matters. For a size 80 belt or size 90 belt, first check whether the number refers to the belt length, waist size or an international size.

For a practical comparison:

1. Put on the trousers you want to wear with the belt.
2. Measure around the waistband, threading the tape through the belt loops.
3. Compare this measurement with the product information.
4. Take into account the position of the middle hole or the adjustable buckle.

A pin buckle usually has several fixed holes. A sliding or plaque buckle can offer a more precise fit. A belt without holes, such as some canvas styles, is generally more flexible.

2. Compare materials carefully

A men’s leather belt is often a sensible choice for workwear, smart trousers and formal occasions. Do check the exact composition, though. “100% leather” means something different from faux leather or bonded leather fibre. Leather also needs different care from textile.

There are several practical options for everyday wear:

• Genuine leather: a smart look with chinos, trousers and suits. Follow the care instructions on the label and avoid washing it unnecessarily.
• Bonded leather fibre: JACK&JONES lists the JACHARRY belt as being made from 100% bonded leather fibre.
• Canvas: a casual polyester belt works well with jeans and leisurewear.
• Cotton and hemp: according to the product information, the LEVI’S Athena Collection is made from 69% cotton and 31% hemp.
• Elastic woven material: a good choice when freedom of movement and a flexible fastening are important.

Check the width too. A belt around 3.5 cm wide will often fit standard belt loops and work with both casual and formal outfits. A wider canvas belt has a more relaxed look.

3. Match the colour and buckle to your wardrobe

A black belt pairs easily with black shoes, dark trousers and workwear. A brown belt goes well with denim, beige, olive green and brown leather shoes. If you want one belt to work with a range of outfits, choose an understated buckle and a medium-dark colour.

A formal belt usually has a subtle buckle and a relatively slim strap. A casual belt can have more texture or a more eye-catching fastening. A women’s belt, men’s belt or unisex belt isn’t defined by its intended wearer alone; the size, width and style are what determine whether it works with your clothes.

Frequently asked questions about buying a belt

How can I tell whether a size 80 or size 90 belt will fit?

Measure around your waist through the trouser belt loops and compare the measurement with the brand’s size guide. A size 80 doesn’t always mean 80 cm of usable length. Check the length from the buckle to the middle hole too.

How long does a leather belt last?

Its lifespan depends on the quality of the leather, how often you wear the belt and how well you care for it. Don’t store a leather belt rolled up for long periods, avoid excessive moisture and follow the instructions on the product label. Faux leather, bonded leather fibre and textile come with different expectations.

Which belt works with both jeans and a suit?

A simple black belt with a buckle, around 3.5 cm wide, is usually a versatile choice. For a suit, opt for a subtle buckle and a smooth finish. With jeans, a brown leather belt, canvas belt or elasticated belt may better suit the more casual look. Match the colour and material to your shoes for a coordinated outfit.
