How to Make a Quick and Easy 1920s Bathing Suit

In honor of the delightful 1920s events we’ve had this Summer, including the Lake Tahoe Gatsby coming up this weekend, I want to share with you a fun little project you can do in an afternoon.

First, though, I’d like to say that Debbie, of VintageDancer, challenged me to make a 1920s swimsuit for this weekend, so we can both go to the Gatsby as bathing beauties.  I was scared to death of constructing one, though, because I really had no idea how to do it.

Enter the research …..

A little bit of reading also revealed that suits were made out of wool knit.  Yikes.  However, they were *also* made out of cotton knit, which I decided to go with for a couple reasons: one, it’s far more comfortable; two, it’s easier to find; three, when it gets wet it won’t be so saggy and weigh as much as wool.

Now to get crafting…

What you will need:

  • A pair of short, tight shorts – any color you like, but navy blue and black were the most common.
  • An X-Large or larger men’s heavy cotton knit shirt – any color, but again, black or blue was common.
  • A belt – optional
  • Knee-high trouser socks
  • Mary Jane shoes

*All of these items are available at WalMart, KMart, Target, or similar stores, except maybe the shoes.

Step One:
You are starting with a men’s x-large shirt.  This shirt should be the heaviest cotton knit you can find, and the hem of it should extend down to your thighs.

Cut the sleeves off, and slice open the side seams.

Step Two:
With the shirt on your dress form (or on you, if you have a friend helping you), pull both sides of the front taught across the form, and mark the strap and underarm curve on the front, allowing at least 1/2″ seam allowance.  You only need to do this on one side.

Use chalk to mark.

Remove the shirt, fold in half length-wise, and cut out the front armscye.

Do the same for the back of the shirt, making sure to match the markings to the front, under the arm.

Lastly, mark and cut the neckline for back and front.

Step Three:
Double-turn the edges of the new armscyes and neckline, and top-stitch them down using either an overlock stitch on your sewing machine, or a serger.  A zig-zag stitch will also work, but be sure not to pull the fabric through the presser foot, as you sew.  Refer to your sewing machine’s book to see which stitches are most appropriate for stretch, jersey fabrics.

ignore that random white thread, pls.

Step Four:
With the shirt on your dress form, pin the sides together, pulling the front and back of the shirt very taut across the form.  Pin both sides evenly.  As you see in the photo, you are taking in quite a lot of fabric.

Stitch the sides using your overlock stitch or serger, and cut off the excess.

Step Five:
Try your suit on.  It should fit the body very tightly, but not uncomfortably.  If it is too loose, take in more at the side seams.  If it is too long, mark your desired length while you are wearing it (to account for the caboose), and hem using your overlock stitch or serger.  The hem should be right about at the hem of your shorts, or just above.

Step Six:
Trim!  There are many examples of fun trimmings to add to your suit – white ribbon applique, patches, bias edging.  I chose to encase the neckline with white bias tape.

Add accessories.  I put a white belt with mine, and will carry a parasol to keep the sun off.  Also, don’t forget the knee-high socks and the shoes.  It seems odd to wear socks and shoes with your swimsuit, but this is what makes the suit look vintage.  I got black, lightweight trouser socks at WalMart, and put on my mary jane dance shoes.

And that’s it!

The preview, before this weekend.

But you know what?  You can make this swimsuit even more easily (but less historically accurate)….

  • Pair your short black shorts with a long-length tank top, like this one from Target
  • put on a white belt at the waist, knee-high black socks and mary jane shoes, 
  • and you’re done.  Seriously.

I hope you found this tutorial helpful!  I’ll have photos to post of use girls at the Gatsby, after this weekend 🙂

    The next time I have a vintage swim event to attend and run out of time I'm totally doing this! So great! Thanks for sharing!

    Great job – love your interpretation!!!

    The use of wool for swimwear does have some practical points: Dyes for protein based fabrics were more colorfast (still are typically, holding up better to sun and surf. I have friends who have made 1860's bathing costumes and they report that water sheeted off the wool far better than cotton, preventing cling and sagging.

    I so wish I had some event to attend that would give me an excuse to use your tutorial – it's really wonderful!

    Frankly, I have been intimidated by vintage swimwear construction (not sure why) but no more! Thank you for such a great tutorial. This would be an awesome trick to tuck into my files for theatrical purposes. Cheap and easy!

    Thank you! I hope you find it useful at least to overcome the fear. It's not completely and utterly historically accurate, but it's a good start. After finishing it I thought "why didn't I just go buy a long tank top!?" and felt rather silly, lol.

    Gorgeous idea – it looks sooo cute!
    Now I just need to figure out how to get lovely sunny weather quick and easy;)

    Question–any suggestions for "support" underneath the top? Did vintage swimsuits have any type of bra sewn to the inside? How to keep that layer from staying wet when the rest of the suit dries out?

    Where did you find your shorts? I just love this little tutorial – can't belive I was intimidated before! I'm doing this before I go swimming next week!

      I believe I got those shorts at Fredericks of Hollywood years and years ago, but any very short, tight-fitting gym shorts will do. Avoid boyshort underpants, though – that's a little *too* short!

    This is pretty fantastic, and could probably quite easily be applied to a men's swimsuit just the same. As someone who's been after a men's swimsuit for quite some time now, I find this incredibly helpful! I may just look into this project sooner than first thought now!

    Kind regards,

    Thank you so much for this. I was trying to get around it in my head. I would still love to be able to make or find a pattern to make it whole as a one piece swimsuit. Have you seen a pattern anywhere? You are a genius!

    I love it.
    I'm currently a waist size of 37 1/2 in. (So it wouldn't look too lovely on me.)
    But, I'm going to get down to a waist size of 26 (or smaller if I'm lucky!) and try this pattern!
