Okay, I admit, summer isn’t here — at least not where I live in Idaho, anyway — but a girl can dream, can’t she? I’m dreaming of summer, imagining myself laying in a lawn chair, and anxiously awaiting the opportunity for more free time to sew!
And today’s project is really just a new take on an older blog post here. When I first designed my swimsuit top, it came with some Marilyn Monroe “booty shorts” style swimsuit bottoms. You might remember seeing this set:
Since then, I created a pattern and tutorial for making a Barbie-sized pair of underpants, which you can make out of jersey fabric — perhaps even using an old pair of panties with elastic still in them — as you can see below:
But when I made today’s bikini project, I used the bodice pattern for the Marilyn Monroe retro bikini, and added straps using 1/4 inch pink elastic. Take a closer look, and you’ll see what I mean:

Then, for the swimsuit bottoms, I’ve used the shorts pattern and created a casing not just at the waist but also at the bottom of each leg of the shorts. Again, a closer look at the swimsuit bottoms will show you what I mean:

So for today’s project, if you want, you can follow the tutorials for making the swimsuit with the green and white striped “booty shorts,” and make a few alterations to shorts to get this overall look:

In all honesty, I wasn’t happy with how the swimsuit bottoms turned out after I made a casing for them. They look too puffy to me. So that’s why I never made a tutorial video showing how to convert the shorts into swimsuit bottoms. But I think it’s time to show off the creative ways you can use my patterns anyway, including this variation on the “booty shorts” or “short shorts” from the first incarnation of this bikini pattern.
Of course you can just use the patterns and tutorials for making the all-jersey fabric bra and underpants you see on Petite Barbie here:

I’m including the links to those tutorials in the bulleted list below, but don’t get confused by the fact that Skipper is wearing the “training bra” version in one of those tutorials. It will work for your Barbies too, as you can see in this image from a couple of weeks ago (Skipper’s “training bra” on my busty vintage Barbie):

The swimsuit bottoms pictured above are an original pair of Mattel Malibu Barbie bikini bottoms. Sorry, I don’t have a pattern that matches them exactly.
But there are so many ways to take my free patterns and make alterations to them!
Now if you’re not good at making alterations, but you’d like to make the all-cotton set with elastic around the bottom of the “booty shorts,” you know what I’m going to recommend, right? I teach a class on Creative Spark called “How to Alter Doll Clothes Patterns” that might be just what you need to help you start thinking “outside the box,” as they say.
But no matter what variation you try, it can be a lot of fun to make a matching bikini set for your Barbie.
Best of luck to you in your summer swimwear sewing adventure! And special thanks to Ann C., whose email on Saturday, March 5th, inspired this blog post.
