Sewing a pocket onto a finished dress takes about 30 minutes and requires only a needle, thread, and scissors

A pocket sewn onto the outside of a dress is called a patch pocket. You cut a rectangle of fabric, fold and press the edges inward, pin it to the dress where you want it, and stitch around three sides. The opening at the top stays open so you can use the pocket. This method works on any dress fabric—cotton, linen, knit, or blends—and doesn't require taking apart any seams.

The pocket sits flat against the dress and is strong enough for everyday use if you sew it with a straight stitch and backstitch at the corners. Most people place pockets on the hip area, roughly 4 to 6 inches down from the waistline and 2 to 3 inches in from the side seam, but you can position yours wherever looks balanced on your dress.

Key Takeaways

  • Cut a rectangle of fabric 5 to 7 inches wide and 6 to 8 inches tall, depending on how large you want the pocket opening to be.
  • Fold all four edges inward by half an inch, press them flat with an iron, and fold the top edge down again by another half inch to create a finished opening.
  • Pin the pocket to the dress, then stitch around three sides with a straight stitch, backstitching at each corner to reinforce the seams.
  • A pocket sewn this way will hold small items like a phone or keys without pulling away from the dress.

Measure and cut the pocket fabric

Start by deciding how wide and tall you want your pocket. A practical pocket is usually 5 to 7 inches wide and 6 to 8 inches tall—large enough to slip your hand into but not so large that it looks bulky on the dress. You can use the same fabric as the dress, a contrasting solid color, or a print that complements it.

Cut a rectangle to your chosen size. If you are using a knit or stretchy fabric, cut the pocket from a stable woven fabric instead—cotton or linen—so it does not sag over time. Write the dimensions on a piece of paper and keep it nearby so you remember them when you position the pocket on the dress.

Fold and press the pocket edges

Lay the rectangle flat on your ironing board. Fold one long edge inward by half an inch and press it with a hot iron. Repeat on the other three edges. The pocket now has all four sides folded under and should look like a smaller rectangle with neat, pressed edges.

Now fold the top edge down again by another half inch and press it. This double fold at the top creates a finished, reinforced opening that will not fray when you use the pocket. The other three sides have a single fold, which is fine because they will be stitched down and hidden against the dress.

Position the pocket on the dress

Try on the dress and use a fabric pencil or tailor's chalk to mark where you want the pocket. Most pockets sit on the hip, about 4 to 6 inches below the waistline and 2 to 3 inches in from the side seam. Mark the top left corner, top right corner, and bottom left corner with three small dots.

Take off the dress and lay it flat on a table. Position the pocket so its top edge aligns with your marks, then pin all four sides to the dress. Use at least four pins—one near each corner—so the pocket does not shift while you sew. Step back and look at the placement; if it looks crooked, unpin it and reposition.

Stitch the pocket to the dress

Thread your needle and tie a knot at the end. Start at the top left corner of the pocket opening. Sew a straight stitch along the left side of the pocket, going down toward the bottom. When you reach the bottom left corner, backstitch two or three times to lock the thread, then continue along the bottom edge.

At the bottom right corner, backstitch again, then sew up the right side. Stop when you reach the top right corner and backstitch two or three times. Do not sew across the top opening—that stays open so you can use the pocket. Tie off the thread on the back of the dress and trim the excess.

If you have a sewing machine, use a straight stitch at medium length (2.5 to 3.0 mm) and sew the same three sides. Machine stitching is faster and stronger, and backstitching at the corners is automatic on most machines. Either way, the pocket is now permanently attached and ready to use.

Reinforce the corners if the pocket will hold heavy items

If you plan to carry keys, coins, or other items that put weight on the pocket, add extra stitching at the top corners. These corners take the most stress when you reach in and out. After you finish the three main seams, sew a small square or triangle at each top corner, stitching over the area two or three times.

You can also sew a second line of stitching half an inch inside the first line, running parallel to it on all three sides. This creates a double-stitched pocket that will last through many washes and years of use. The extra time is worth it if the dress is one you wear often.

Frequently Asked Questions

Can I sew a pocket onto a stretchy dress fabric?

Yes, but cut the pocket from a non-stretchy fabric like cotton or linen so it stays in shape. If you cut the pocket from the same stretchy fabric as the dress, it will sag and lose its shape after a few uses. The contrast between the stable pocket and the stretchy dress is normal and invisible once the dress is on.

What if I sew the pocket on crooked?

Carefully cut the stitches with a seam ripper or small scissors and remove the pocket. Press out the old stitch holes with an iron and a damp cloth. Reposition the pocket and sew it again. The old holes will fade, especially if you sew the new seam slightly to the side of the old one.

How do I keep the pocket opening from fraying?

The double fold at the top (folded twice and pressed) prevents fraying because the raw edge is tucked inside. If you want extra protection, explore a thin line of clear fabric glue or fray check liquid along the inside of the opening before you sew the pocket down. Let it dry completely before sewing.

Can I add a pocket to a dress that is already hemmed?

Yes. A patch pocket sits on top of the finished dress, so the hem does not matter. Just make sure the pocket does not extend below the hem or it will look unbalanced. Position it high enough that the bottom edge of the pocket is at least an inch above the hemline.
