If you love swimming but prefer a modest look over a bikini, then check out this DIY tutorial to learn how to make a swim dress.


Swim dresses are hard to find in stores, and when you do find them, they are very expensive. But you can easily make your own from an oversized water sports t-shirt.

Tools and materials:

Tracing a t-shirt to make the pattern

1. Cut the swim dress bodice

Lay your oversized water sports t-shirt on your work surface and place your old regular t-shirt on top of it, folding in the sleeves of your regular t-shirt. 

Trimming the fabric to make the swim dress

Trim the oversized t-shirt to the size of your regular t-shirt.

If you want to add side panels in a contrasting fabric, then trim the oversized t-shirt to exactly the size of your regular t-shirt.


But if you do not want to add side panels to your swim dress, then trim the oversized t-shirt to the size of your regular t-shirt, adding a seam allowance.

2. Cut the swim dress sleeves

Lay the sleeves of your regular t-shirt on top of the sleeves of your oversized t-shirt and cut the oversized sleeves to match the regular ones, adding a seam allowance.

3. Make swim dress side panels (optional)

From a contrasting fabric, cut two rectangular side panels with a pointed top (piece A in the image above.)


Estimate the width you will need for the side panels to make the swim dress comfortable. Make the length fit from the bottom of the swim dress to the underarm. For this demo, the side panels were about 4 inches wide, including the seam allowance.


If your side panel fabric is finished on one edge, make that the bottom of your panel (B in the image) so you won’t need to hem it.

How to sew a swim dress

With right sides facing in, sew one side panel to each side of the front of the swim dress, from the hem line to the underarm.

Sewing the side panels of the DIY swim dress

Then sew the back of the swim dress to the side panels.

Sewing the sleeves for the swim dress

Sew the inside seam of each sleeve closed. Then insert the sleeves into the bodice of the dress and sew the sleeves in place.

With the hem and neckline of the oversized water sports t-shirt already done, the only thing left was the side panels and sleeves, which made this DIY swim dress a really quick project.

    I'm glad I'm not the only one that likes to swim without body parts hanging out or showing. Good job.

    • Thanks! I wanted to make an affordable and easy option. To me, it's all about choice! Wear what you feel good in and what works for the activities you want to do. ♥ I enjoy watersports so this works for that along with swimming!
