Rash Guard and Boy Shorts: Swim Patterns

Rash Guard and Boy Shorts: Swim Patterns

I’m been meaning to show you forever: Bella’s rash guard and boy shorts. Patterns used are the Monaco Swim Trunks and Hang Ten Rash Guard from Peekaboo Patterns. (Affiliate links.) I made this suit about October of last year. We were going to an event with indoor swimming, and I thought it would be easier to sew a new swimsuit than to unpack summer clothes from the barn.

Caroline at Sew Can She showed off her swimsuits using the exact same patterns Saturday. As I was reading her post; I looked outside to see my little girl wearing hers. So I took some quick pics with my iPod, and here it is!

I modified the shorts length to a boy shorts cut. They are fully lined, giving this swimsuit a nice weight. For the top I added just a bit of negative ease in the torso and sleeves to keep it more snug to the body. It’s being worn as an actual swim top rather than to cover a swim top; and I didn’t want it to float up. I recommend this mod for girls if there won’t be a swim top under. The front is also fully lined, and I added 1″ to the length.

I didn’t have enough fabric to cut my pieces on fold, so there is a center seam in the front and back. The print disguises it some so I’m not beating myself up.

When Bella went to church camp, our pastors wife said she really loved it and wanted one for her 12 year old daughter. It made me feel so good that she said that. If I ever have time I’m going to make her daughter one just because she made my day.

I love, love, love these patterns and will continue using them for the younger kids. With Bella sizing out of Peekaboo swim patterns, we’ll be moving onto Jalie patterns for her soon. I already have a couple in stash and can’t wait to try them. Id like to make myself a swimsuit too, but I want a steel cage to put everything where I want it and keep it there. I’m pretty sure I will be impossible to satisfy…but you never know.

Fabric: FunkiFabrics Action Painting Black and nude lining. This is better than any swim fabric I’ve ever touched. Perfect recovery even when I stretched it as hard as I could. Nice weight and zero fading in chlorine. Survives wicked abuse.

Modifications: Fully lined shorts and top is front lined. Swim trunks have been shortened to boy shorts. Negative ease and length added to top.

Hello. I'm Amy and I'm addicted to sewing. I borderline-hoard fabric, buttons, & patterns. Sometimes I wish I could pile my fabric up on the floor and just roll in it!

    Oh, wow! You continue to take challenges! I think the modest swimsuit is a must for little girls, and this one is great. Great fit and seems very comfortable. And the print is just fantastic. It looks like a high-end swimsuit!
    I love it and I want it for my 5 years old daughter too. (wink,wink) ;)

    So cute!! The boy short mod was perfect!!! Does adding negative ease mean you take in the seam? That fabric was the perfect fabric for adding seams in as it is so well disguised!!! Great job Amy; if Bella likes it then you know it’s good!!!!!!

    Only you would think it was easier to whip up a new bathing suit rather than a. to go and buy a new one or 2. try and find it in boxes still needing to be unpacked. That’s one of the things I love so much about your and your blog. You always make sewing sounds so easy!

    I love the print! I have seriously found even at the youngest making a swimsuit is the only way to go. Every time I put a store bought one mine her whole tush or top is hanging out..

    Great swim suit Amy! The fit looks perfect and the style is not only modest, but functional and flattering. I need to check out that fabric shop. My oldest is having trouble finding a modest suit in a print she likes.
