What is a dart? Bust, waist and fish darts explained
What is a dart in sewing? A stitched fold tapering to a point that shapes cloth to the body. Bust, waist and fish darts, and how a dart differs from a tuck.
InspirationA dart, defined
A dart is a fold of fabric stitched along a tapering line that ends in a point. It takes out width in one place and turns flat cloth into a shape that follows a curve, such as the bust, the waist or the shoulder blades. From the outside it looks like a short seam that fades to nothing; inside there is a small wedge of folded fabric.
The point of a dart aims at the fullest part of the curve it is shaping but stops a little short of it, so the fabric eases smoothly over the body instead of forming a peak. Getting that distance right is a large part of what makes a fitted top look good.
The kinds, named by where they sit
Darts are named by position. A single garment may use one kind or several together.
- Bust dart: runs from the side seam towards the bust, roughly level or angled slightly upwards.
- French dart: a long diagonal dart starting low on the side seam and angling up towards the bust.
- Waist dart: a vertical dart rising from the waist towards the bust on a top, or dropping towards the hip on a skirt.
- Back waist dart: shapes the back into the waist so a fitted top does not stand away from the spine.
- Shoulder or back neck dart: gives room over the shoulder blades, common in tailored jackets.
- Fish dart: a double-pointed dart, wide at the waist and tapering both upwards and downwards, used where there is no waist seam. Its outline looks like a slim fish, hence the name; it is also called a contour dart.
- Elbow dart: a small dart at the back of a fitted long sleeve so the arm can bend.
Dart, tuck, pleat or gathers?
All four control fullness, but they do it differently. A dart tapers to a point and gives permanent shaping. A tuck is a stitched fold of even width, often decorative, such as the narrow pin tucks on a yoke; a released tuck is stitched part of the way and then left open so fullness falls below it. A pleat is folded and pressed, usually stitched only at the top, so the fabric can swing open as you move. Gathers draw a wider piece into a narrower seam in many tiny folds.
So a fitted kameez front might use bust darts, while a frock uses gathers or pleats where the bodice meets the skirt. Our article on what a bodice is shows where those joins fall.
Do kameez have darts?
A traditional kameez is often made with no darts at all. It is cut fairly straight, shaped a little at the side seams, and relies on ease for comfort. Fitted kameez, kurtas worn close to the body and most Western dresses use bust and waist darts, or long princess seams that do the same job without separate darts.
Whether you want them depends on the look and the fabric. Darts give a neater, more tailored line, but they can show on sheer fabric and interrupt a large print. Our guides to choosing a kameez silhouette and how loose a kameez should be help you decide how fitted to go.
Asking for darts, or for none
In your order, say what you want in plain words: “relaxed, no darts”, or “bust darts for a closer fit through the body”. For darts to sit correctly, shoulder to bust point and the distance between bust points help, alongside the usual bust, waist and hip; how to measure for a made-to-measure dress shows how to take them. Through our custom stitching service the shaping is agreed in writing before cutting. Ask for a quote and add your preference in the notes.
Common questions
Why does a dart end in a bubble?
A pucker at the point usually means the stitching stopped too abruptly or the dart was too wide for the curve. A well-made dart tapers gradually and finishes with the last stitches running right along the fold.
Do stretch fabrics need darts?
Usually fewer, because a knit stretches over curves on its own. Many jersey tops have none, while woven fabrics need darts or seams to follow the body closely.
Do darts show on printed fabric?
They can break up a large print or a stripe, which is why some dressmakers prefer seams or extra ease on bold prints. On small or busy prints they are hard to spot.
