A polyester buckle is the most versatile choice when the belt has to continue the colour and character of the buttons. It is cast from polyester resin – the same material used for fashion buttons – and can therefore reproduce a mother-of-pearl, horn, tortoiseshell, marble or stone effect. Polkom is a manufacturer of buttons and buckles with over 30 years of experience and makes polyester buckles in any shape and any colour, in sizes from 2 to 6 cm, with or without a prong. In this article you will see the shapes and effects one by one, a selection table and which garments each option suits.
Why a polyester buckle
A metal buckle brings shine, a covered buckle disappears into the fabric, and a polyester buckle sits in between: it is a decorative element in its own right, but in tune with the collection. Its greatest advantage is that it can be coloured and shaped with almost no limits.
- Any colour – the buckle is dyed to a sample of the fabric or to the button of the model.
- Any shape – from the classic rectangle to asymmetric forms, to your design.
- Natural effects – mother-of-pearl, horn, tortoiseshell, marble and stone without using natural materials.
- Light weight – a polyester buckle is lighter than a metal one and does not weigh down the belt of a dress or coat.
- A set with the buttons – the buckle and the polyester buttons can come from the same series and effect.

The shapes one by one
Rectangular
The rectangular polyester buckle is the classic for coat and trench coat belts – for women and men. It follows the line of the belt and accentuates the waist without unnecessary decoration. In dark brown horn or with a pearl effect it looks especially elegant.

Round
The round buckle is more feminine and is chosen for dresses, tunics and light summer coats. With a brushed texture or a pearl effect it looks contemporary, with a horn effect it looks classic.

Octagonal
The octagonal shape sits between the circle and the square – geometric, but without sharp corners. It gives character to trench coat belts and men's coats and stands out without being loud.

Rounded
The rounded shape – a rectangle or square with soft corners – is the most universal. It suits both women's and men's models and does not wear the fabric during everyday use.

Asymmetric
The asymmetric buckle is a fashion-forward, designer shape. It is an accent in itself and suits designer collections, dresses and belts where the buckle is the centre of the model.

Effects and surfaces
The effect is created when the polyester is cast and coloured, so each buckle has a slight natural variation in its pattern – just like the natural materials it imitates.
| Effect | What it looks like | Suitable for |
|---|---|---|
| Mother-of-pearl | soft pearly sheen, shifting light | dresses, light coats, evening models |
| Horn | dark and light veins like natural horn | wool coats, trench coats, menswear |
| Tortoiseshell | spots in brown, gold and amber | trench coats, brown and beige collections |
| Marble | flowing veins in two or more colours | modern coats and dresses |
| Stone | matt, slightly grainy surface | grey and neutral collections, minimalist style |
| Brushed | fine parallel lines, matt look | contemporary urban models, men's coats |
A pearl effect is not genuine mother-of-pearl – the difference is explained in the comparison mother-of-pearl or polyester buttons, and the same applies to buckles. How colour is matched to a sample is explained in buttons in the colour of the fabric.
Sizes from 2 to 6 cm
We make polyester buckles in sizes of 2, 3, 4, 5 and 6 cm according to the width of the belt. The inner opening should be equal to the width of the belt or slightly wider, and for a double wool coat belt also taller, so the belt passes freely.
- 2 – 3 cm – dresses, tunics, thin belts and cuff details;
- 4 cm – trench coats, jackets and trouser belts;
- 5 – 6 cm – belts on women's and men's coats and trench coats.
For an exact choice by width, see belt buckle sizes.
With or without a prong
Polyester buckles are made in both versions. Without a prong the belt is threaded and adjusted freely – the solution for coats, trench coats and dresses with a tie belt. With a prong the belt fastens in a hole and stays in an exact position – more practical for trouser belts and tighter-fitting models. More about the parts of a buckle can be found in buckle terms and parts of a buckle.
Which garments
- Women's coats and trench coats – rectangular and rounded shapes in horn, tortoiseshell or pearl effect;
- Men's coats and trench coats – rectangular and octagonal buckles in horn, stone or a brushed surface;
- Women's dresses – round, rounded and asymmetric buckles in pearl and marble;
- Belts – stand-alone belts for the collection, with or without a prong.
If you are looking for a buckle that repeats the fabric completely, also take a look at fabric- or leather-covered buckles. A full overview of buckles by material and mechanism is in types of buckles.
Care and durability
Polyester buckles do not rust and do not stain the fabric. With the right technology they withstand washing and dry cleaning together with the garment, so they are also suitable for coats that are cleaned regularly. For belts worn every day we recommend a thicker profile and rounded edges – this way the buckle does not rub the fabric and keeps its effect for a long time.
How to order polyester buckles
- Choose the shape and size according to the width of the belt.
- Choose the effect and send a sample of the fabric or button for the colour.
- Specify whether the buckle has a prong or not.
- Approve the sample on the actual belt.
- After approval, series production begins.
