If you’re short on time, here’s a quick answer to your question: Darts in sewing are folds sewn into a garment to shape the fabric to fit the body. They allow flat fabric to take on a three-dimensional shape.

Darts are an essential technique in constructing tailored clothing. In this comprehensive guide, we will explain everything you need to know about sewing darts. You’ll learn what darts are, why they are used, the different types of darts, how to sew them properly, and tips for perfect dart placement.

What Are Darts?

Darts are essential elements in sewing that help create shape and contour in garments. They are triangular folds of fabric that are sewn into the fabric to provide shape and a better fit. Darts are commonly used in both garment construction and pattern making to create a more tailored and flattering silhouette.

Definition and Purpose of Darts

Darts are small folds or tucks that are stitched into the fabric to add shape and contour. They are typically wider at one end and taper to a point, resembling a triangle. The purpose of darts is to remove excess fabric and create a more fitted shape.

They are commonly used to shape the bust, waist, hips, and other areas of a garment to ensure a better fit and enhance the overall look of the garment.

Darts are often found in bodices, waistbands, and skirts, but they can be used in various areas depending on the design and desired fit. They are an essential technique in sewing and pattern making, especially when working with fabrics that do not have natural stretch or drape.

How Darts Create Shape in Fabric

When a dart is sewn into a fabric, it allows the excess fabric to be taken in, creating a three-dimensional shape. The wider end of the dart is positioned at the area where more fabric needs to be removed, such as the waistline or bust.

As the dart is stitched, the fabric is folded and sewn together, creating a tapered shape that contours to the body.

Darts can be strategically placed to create different shapes and effects. For example, darts can be used to create a more defined waistline, enhance the bust, or provide ease in the hips. They can also be used in combination with other techniques, such as pleats or gathers, to achieve desired results.

Understanding darts and how they work is important for anyone involved in garment construction or pattern making. They are a fundamental technique that helps achieve a better fit and shape in garments, ensuring that they flatter the wearer’s body.

Types of Darts

Single-Point Dart

The single-point dart is the most commonly used type of dart in sewing. It is a triangular fold of fabric that tapers to a point at one end. This type of dart is often used to shape the bust area in women’s garments, creating a more fitted look.

It can also be used to shape the waist or hips in garments.

Double-Point Dart

The double-point dart, also known as a fish-eye dart, is a dart that tapers to a point at both ends. This type of dart is used when shaping curved areas, such as the waist or hips. It creates a more contoured fit and adds shape to the garment.

Double-point darts are commonly used in dresses, skirts, and pants.

Slash and Spread Dart

The slash and spread dart is a unique type of dart that involves cutting and spreading the fabric to create shape. It is often used when a single-point or double-point dart is not suitable for the desired design.

This technique allows for more flexibility in adding shape to garments and can create interesting design elements. It is commonly used in advanced sewing projects and couture garments.

Understanding the different types of darts in sewing is essential for achieving a well-fitted and professionally finished garment. Each type of dart serves a specific purpose in shaping and contouring the fabric to fit the body.

Whether you are a beginner or an experienced sewer, knowing how to use darts effectively will elevate your sewing skills and give your garments a polished look.

Dart Placement

When it comes to sewing, darts are essential for creating shape and contour in garments. They are folded fabric tucks that help shape the fabric around curves, creating a more fitted and flattering look. Dart placement is crucial to achieve the desired fit and style in different types of garments.

Let’s explore how darts are placed in tops, pants, skirts, and dresses.

Darts on Tops

Darts on tops are typically located around the bust area to provide shape and a better fit. The placement of these darts may vary depending on the design and style of the top. They are commonly found on blouses, shirts, and dresses with fitted bodices.

The position and length of the darts may be adjusted based on individual body measurements and personal preferences.

Darts on Pants

Darts on pants are primarily found in the back of the garment, near the waistline. They help contour the fabric around the hips and provide a more tailored fit. These darts ensure that the pants sit comfortably on the body and do not create any unsightly wrinkles or bulges.

The placement and size of darts on pants may differ depending on the style, such as straight-leg pants, trousers, or jeans.

Darts on Skirts and Dresses

Skirts and dresses often have darts to shape the fabric around the waist and hips. These darts can be found on the front, back, or both sides of the garment, depending on the design. The placement of darts on skirts and dresses is crucial for achieving a flattering silhouette and ensuring a comfortable fit.

The length and position of the darts may vary based on the style, such as A-line, pencil, or flared skirts.

It’s important to note that dart placement may vary depending on individual body measurements and garment patterns. It’s always a good idea to consult a sewing pattern or seek professional advice to ensure accurate dart placement for the best fit and style.

How to Sew Darts

Mark and Pin Fabric

Before sewing darts, it is important to mark and pin the fabric accurately. This will ensure that the darts are sewn in the right place and create the desired shape. To mark the dart, use a fabric marker or tailor’s chalk to draw a straight line from the widest part of the dart to the tip.

This line will serve as a guide for stitching. Next, pin along the drawn line, making sure that the pins are perpendicular to the line and secure the fabric layers together. This will prevent any shifting or slippage during the sewing process.

Stitch the Dart

Once the fabric is marked and pinned, it’s time to stitch the dart. Start sewing from the widest part of the dart and stitch towards the tip, following the marked line. Use a regular straight stitch or a slightly longer stitch length to ensure secure and even stitches.

As you sew, remember to backstitch at the beginning and end of the dart to secure the stitches. Take your time and sew carefully, keeping the fabric flat and smooth as you go.

Pro tip: If you’re sewing a dart on a delicate or lightweight fabric, consider using a stabilizer or tissue paper underneath to prevent any puckering or distortion.

Press Completed Dart

Once the dart is stitched, it’s important to press it to achieve a professional finish. Set your iron to the appropriate temperature for the fabric you’re working with, and press the dart from the wrong side.

Place a pressing cloth or a piece of scrap fabric over the dart to protect it from direct heat. Press firmly and evenly along the stitched line, using steam if necessary. This will help the dart lay flat and give it a crisp, polished look.

Pro tip: To ensure a sharp point at the tip of the dart, use a tailor’s ham or a rolled-up towel underneath the fabric while pressing.

By following these steps, you’ll be able to sew darts with precision and achieve a tailored fit in your garments. Remember, practice makes perfect, so don’t be discouraged if your first few attempts aren’t flawless.

With time and experience, you’ll master the art of sewing darts and create beautifully fitting garments!

Tips for Sewing Perfect Darts

When it comes to sewing darts, attention to detail is key. Darts are small, triangular folds that are sewn into fabric to create shape and contour in garments. They are commonly used in areas such as the bust, waist, and hips to give a tailored fit.

To ensure your darts are precise and well-executed, here are some valuable tips to follow:

Use Interfacing for Structure

Interfacing is a material that is sewn or fused onto the wrong side of the fabric to provide stability and structure. When sewing darts, using interfacing can greatly enhance the overall appearance and durability of the garment.

The additional layer of interfacing helps to prevent the fabric from stretching or distorting, resulting in clean and crisp dart lines. It is particularly useful when working with lightweight or stretchy fabrics.

Trim Bulk for Neat Finish

After sewing the dart, it is important to trim the excess fabric to reduce bulk and achieve a neat finish. This step helps to eliminate any visible bumps or lumps that may be created by the folded fabric.

To trim the excess fabric, use a sharp pair of scissors and carefully cut close to the dart stitching. Be cautious not to cut into the stitching or the fabric itself. Trimming the excess fabric will give your darts a professional look and ensure a smooth and flattering fit.

Match Dart Legs Evenly

One common challenge when sewing darts is ensuring that the dart legs are evenly matched. Uneven dart legs can result in a distorted and ill-fitting garment. To avoid this, it is crucial to mark the dart legs accurately and match them precisely during sewing.

Use tailor’s chalk or a fabric marker to mark the dart placement on both the fabric layers. When sewing, align the marked lines carefully and secure them with pins or basting stitches before sewing. Taking the time to match the dart legs evenly will contribute to a polished and professional finish.

By following these tips, you can elevate your dart sewing skills and achieve impeccable results in your garment construction. Remember, practice makes perfect, so don’t be discouraged if your first attempts are not flawless. With time and experience, you’ll become a master at sewing perfect darts!


Darts play a crucial role in shaping flat fabric to conform to the contours of the body. Learning how to properly sew and place darts will take your sewing skills to the next level. With the techniques covered in this guide, you’ll be able to sew darts with confidence for a perfect, tailored fit every time.
