Three ways to add pockets to any garment

A well-placed pocket can make a handmade garment feel far more useful, comfortable, and personal. It gives you somewhere to keep a phone, keys, tissues, or a tape measure, while also adding an opportunity to play with colour, texture, and proportion.

You do not need a pocket piece included in the sewing pattern to create one. With a little planning, pockets can be added to dresses, skirts, trousers, cardigans, jackets, and even simple tops. The best style depends on the garment’s shape, fabric weight, and how much structure you want the finished pocket to have.

Before cutting into your project, consider what the pocket needs to hold and whether it should blend into the garment or become a feature. The three approaches below cover practical, beginner-friendly options as well as more polished finishes for confident sewists.

Start with the garment and its fabric

Pocket placement should work with the garment’s existing lines. On a dress or skirt, the side seam is usually a natural position for an in-seam pocket. A patch pocket can sit on the front of a shirt, jacket, or cardigan, while a welt pocket suits tailored garments where a discreet finish is important.

Fabric choice affects the pocket’s behaviour. Lightweight cotton, viscose, and rayon can usually support a soft patch or in-seam pocket, but bulky wool or sweatshirt fleece may need a smaller pocket bag to prevent sagging. If your fabric frays easily, finish the raw edges before assembly or use a lining fabric for the pocket bag.

Think about pocket depth as well as width. A pocket that is too shallow can let belongings fall out, while one that is too deep may pull the garment down. A useful everyday pocket often reaches around 15–20 cm below its opening, but proportions should be adjusted for the wearer and the garment.

Add a simple patch pocket

A patch pocket is the most visible and adaptable option. It is made as a separate fabric shape, finished around the edges, and stitched directly onto the garment. Because the construction is straightforward, it is a good choice for beginners and an easy way to introduce contrast fabric, embroidery, piping, or decorative topstitching.

To draft one, place a hand over a piece of paper and trace a shape slightly wider than the hand, adding room at the sides and base. Add a curved lower edge, a straight or gently shaped opening, and a seam allowance around the sides and bottom. The top edge needs a deeper allowance so it can be folded, pressed, and stitched securely.

Finish the upper edge first, then press the remaining seam allowances to the wrong side. For a curved base, clipping or grading the seam allowance will help the pocket lie flat. Pin it in position, checking that both pockets are level if you are adding a pair, and sew close to the edge and again slightly inside the first line for strength.

Patch pockets are especially useful on oversized shirts, utility jackets, pinafore dresses, and cardigans. They can also rescue a plain garment: use a floral scrap on a solid linen dress, or match the pocket to a contrast binding or waistband. The Willow Wrap Cardigan sew-along is a helpful example of how practical details can work with a comfortable layered garment.

Hide an in-seam pocket

An in-seam pocket is inserted into an existing side seam, making it one of the least noticeable ways to add storage. It works particularly well on skirts, dresses, wide-leg trousers, and loose-fitting tops. Since the pocket opening follows the seam, the exterior remains clean and uninterrupted.

Create a pocket bag pattern by drawing an opening around 15–18 cm long, followed by a rounded pouch large enough for the intended contents. Trace the shape onto paper, adding seam allowance around the curved edge and the opening. Cut two mirrored pocket pieces for each pocket, ideally from a smooth, lightweight fabric that will not add unnecessary bulk.

To install it, mark the pocket opening on both side-seam pieces. Stitch each pocket bag to its corresponding garment section, right sides together, and press the seam towards the pocket. Then sew the side seam and pocket bag in one continuous line, pivoting carefully at the point where the opening meets the seam.

Secure the top and bottom of the pocket opening with a short line of reinforcing stitches. If the garment is fitted, check that the pocket does not pull the side seam open when filled. A stay tape or narrow strip of fusible interfacing along the opening can provide extra stability in soft or stretchy fabric.

Create a neat welt or hidden pocket

A welt pocket gives a more tailored appearance. It has a narrow, finished opening, usually with a pocket bag hidden behind the garment. This method is suitable for trousers, coats, waistcoats, structured skirts, and jackets, although it requires accurate marking and careful pressing.

For a simpler version, consider a curved or angled slash pocket. Mark the opening on the garment, apply interfacing behind it, and sew a facing or binding around the cut edge. The pocket bag is then attached to the facing and secured to the garment’s side or front. This design can look refined without requiring the full precision of a traditional double welt.

Always test the technique on a fabric scrap first. Make a small sample using the same interfacing, thread, and pressing temperature as the garment. This reveals whether the opening stretches, whether the pocket bag shows, and whether the fabric can support the stitching.

A hidden pocket can also be added inside a jacket or bagged lining. Sew a small zip pocket or patch pocket to the lining before closing the garment. It will not replace an accessible outer pocket, but it is excellent for valuables and keeps the outside design uncluttered.

Compare the options before cutting

The right pocket style depends on the look you want, the fabric available, and your confidence with construction. Use the guide below to choose a practical starting point.

Pocket style	Best for	Difficulty	Main advantage	Watch for
Patch pocket	Shirts, jackets, cardigans, dresses	Beginner	Easy to customise and reinforce	Uneven placement or sagging
In-seam pocket	Skirts, dresses, trousers, loose tops	Beginner to intermediate	Discreet and comfortable to use	Side seams pulling out of shape
Welt or hidden pocket	Tailored trousers, coats, waistcoats	Intermediate to advanced	Polished, low-profile finish	Inaccurate marking and bulky layers

Whatever style you select, make a paper mock-up first. Tape it to the garment and place your hand over the opening. Walk around, sit down, and check that the pocket is reachable without distorting the garment. This small test can prevent hours of unpicking.

Good pocket construction also depends on reliable basic equipment. If you are building a beginner sewing kit, these essential sewing tools will make marking, pressing, trimming, and accurate stitching much easier.

Strengthen the finish

Pockets receive repeated stress, especially when they hold keys or a mobile phone. Reinforce the top corners of patch pockets with a bar tack, a short triangle of stitching, or a small piece of decorative tape. Backstitch securely at the beginning and end of every pocket seam.

For in-seam pockets, grade the seam allowances so the pocket does not form a ridge on the outside. Overlock or zigzag the raw edges, then press the pocket bag towards the front or back consistently. A line of understitching around a pocket facing can stop it rolling out during wear.

Topstitching is both decorative and practical. Two parallel rows can stabilise a patch pocket, while a narrow line around a curved opening can keep the edge crisp. Match the thread for a quiet finish, or choose a contrasting shade when you want the pocket to become a deliberate design feature.

Make the pocket work harder

• Match the pocket fabric to the garment’s weight, or choose a lighter lining for a softer result.
• Add interfacing to openings that may stretch, especially in knit or loosely woven fabric.
• Test the pocket depth with the objects you plan to carry.
• Press at every stage and use a pressing cloth when working with delicate or heat-sensitive fabric.
• Check symmetry by measuring from the hem, waistline, and centre front rather than relying on visual placement alone.

Put your pocket plan into practice

Adding pockets is a useful way to adapt commercial or indie sewing patterns to suit real life. A pocket can change how often you wear a garment, make a simple project more functional, and give you a small space to experiment with fabric scraps and construction details.

Choose one method that matches your current skill level, draft the pocket on paper, and make a sample before cutting the final fabric. Then take your time with pressing, reinforcement, and placement. Start with a patch pocket if you want an approachable project, or move towards an in-seam or welt design when you are ready to refine your technique.
