Have you ever noticed the sleek, hidden pockets on a tailored jacket or a pair of smart trousers? These aren’t just any pockets; they are often “welt pockets,” a hallmark of quality craftsmanship in clothing. Unlike pockets sewn onto the outside, welt pockets are built into the garment, creating a clean and sophisticated look.

This article will guide you through everything you need to know about welt pockets: what they are, how to spot them, and why they are a sign of a well-made garment. Get ready to appreciate the finer details in your wardrobe!

1. What exactly is a welt pocket?

A welt pocket is like a secret pocket. It is made inside your clothes, not stuck on the outside. This type of pocket is called an inset pocket.

You mostly see a clean flat opening, like a neat slit, where the pocket opens. Think of it like a small letterbox slot in a door. This slot is in your jacket or pants, and it’s for your hand or small items. The main part of the pocket is hidden inside. This makes it different from pockets that are like a bag sewn on top of the clothes.

The special part of a welt pocket is called the “welt.” A welt is a small, neat strip of fabric. It runs along the edge of the pocket opening. Sometimes there is one welt, and sometimes there are two fabric welts.

These welts make the pocket opening look very tidy and finished. They also reinforce the opening, making it more durable and resistant to tearing. The welts are usually made from the same fabric as the clothes. Sometimes, a different fabric is used for style.

2. Key features & how to spot a welt pocket

2.1 The clean opening

The most telling feature is a clean, straight slit on the garment. Along the edge of this slit, you’ll see one or two narrow, finished strips of fabric. These are the “welts”. The pocket opening can be straight across or sometimes a little bit slanted. It does not usually have a big flap covering it, and it’s not a bag shape sewn on top.

2.2 The hidden pocket bag

Remember, the part that actually holds things is a hidden pocket. So, if you can only see opening and not the whole pocket bag from the outside, it might be a welt pocket.

2.3 Its flat appearance

Welt pockets usually lie very flat pocket against the clothes. They doesn’t stick out or bulge like a pocket that is sewn on top. That kind of pocket is often called a patch pocket. This flat design gives the clothes a smooth look.

2.4 The flat appearance

Unlike patch pockets that are sewn on top of clothes, welt pockets lie flat against the garment. This creates a smooth, streamlined silhouette without adding bulk.

This is sometimes called a flapped pocket. The flap can be worn hanging out to cover the pocket, or sometimes it can be tucked inside the pocket to show the welts. The flap acts as a pocket cover. You often see these on suit jackets or outdoor coats.

6. Why use a welt pocket?

8. How are welt pockets made?

Making a welt pocket is quite a skillful job for a tailor or someone who sews. Here are the basic welt pocket construction steps:

  1. Careful cutting: First, a very precise cut is made in the main fabric of the clothes where the pocket will be.
  2. Making welts: The fabric strips for the welts are prepared and sewing welts carefully to the edges of this cut.
  3. Pocket bag: A pocket bag is made from lining fabric. This is part of pocket bag making.
  4. Attaching bag: This pocket bag is then sewn to the welts on the inside of the garment.
  5. Finishing: Everything is pressed and sewn neatly to look perfect. Often, a special fabric called interfacing is used inside the welts. Interfacing is a bit stiff. It helps the welts keep their shape and makes them stronger. This interfacing in pockets is a common technique.
