A Jalie Bikini: 3351 Swim Shorts and 4136 Crossover Top

Side pocket of shorts

Pattern Background

Jalie 3351

This pattern can be used for either running or swim shorts. It has a wide waistband, side panel pockets, and built in briefs.

Per Jalie, the waistband hits around the navel for kids, a few inches below the navel for teen and smaller adult sizes, and got up around the navel again for the larger adult sizes.

The size range goes from F (2T) all the way to FF (women’s size 22/ euro 52).

This pattern is out of print now so it is only available as a PDF.

This fully lined bikini pattern has both a scoop neck and crossover versions for the top. The bikini bottoms include both a lower rise version and higher waisted versions, one of which has a self fabric tie detail.

Size range goes from 2T to 2X. Like with a lot of the newer Jalie pattern releases there’s also a PDF only version that goes from 2T to 5X, and a plus size version for 1X-5X.

Fit and Alterations

Per my hip measurement I made a size CC. The ease was perfect.

I added 2.5” of height to the center back seam, tapering to nothing at the center front. I also added 3/8” width to the front inseam for my fuller thighs. When I was adding the elastic I sized down a couple of sizes per the elastic cutting length chart. They feel snug and secure without digging in.

After making a test version I lowered the rise 1”. They sat at the navel and just seemed too big and matronly when worn with a bikini top. They would have been fine if worn with a rashguard top or tshirt.

I made a size Y. I sized down to a W for the band. I compared my underbust measurement to the size chart and W was the closest matching measurement, so that’s what I cut.

Fabric and Materials

I used a Lycra purchase from the Elingeria sometime back in 2012 (yes it has been sitting in my stash all this time). I didn’t have quite enough (these were scraps from another project from long ago) so I cut the side panel, waistband facing, and brief from a white swimwear fabric I found on Amazon. I should have read the description better because it’s kind of shimmery and I prefer matte fabrics for swimwear, but so little of it peeks out that it doesn’t really matter.

The lining for the crotch was a swimwear lining recently purchased on sale from Emma One Sock.

The 3/8” braided elastic was from the Amazon seller Mandala Crafts.

For the bikini top I used a swimwear lining fabric from Payless Fabrics on Amazon.

Construction

The instructions are excellent and I had no issues. I really like how the waistband is constructed. The facing is cut shorter than the outside waistband, which causes the seam where the elastic, outer waistband, and waistband facing meet to be folded entirely to the inside. This completely eliminates bulk at the upper edge of the waistband, and if you’re using a different fabric for the waistband facing it won’t show through at all.

I will say that my life was made significantly easier when turning up those hems for the pockets and hems by using Design One fusible stay tape. This tape is exactly 3/8” wide so if you apply it directly along the edge you get a nice guide for folding the hem before removing the paper. I just doubled it up to make it 3/4” wide for the front and back shorts hem. It not only made turning up the hem far easier on this slippery synthetic fabric, but also made cover stitching way easier. The final result still maintained its stretch. 10/10 recommend!

Like with the shorts, the instructions were excellent. I particularly liked the band construction. You zigzag the elastic to one edge, fold the other edge of the fabric up around the elastic snugly, zigzag again, trim, and then sew it directly to the rest of the top. Very neat and completely eliminates the elastic rolling inside during wear or laundering.

Conclusion

I’m extremely happy with the shorts. They fit and feel great! I wanted something I could confidently wear to the beach while playing with my little boy and these are perfect for that. Unlike with a skirt they won’t ride up in the water, and you get plenty of coverage if you’re self conscious about your lower half (which I definitely am post baby). The brief is full coverage and stays in place really well.

The bikini top feels secure and comfortable to wear. I think I am a 36C now (not sure since I haven’t worn a proper underwired bra in years now) and I feel like it gives good support. I have plans to make it as a bra top as well, because my toddler still nurses on occasion and the crossover styling makes that very convenient. (Jalie actually has a post on converting this pattern to an unlined bra top, though I would likely do a lined version for extra support.)

Jalie 3243: Pull-on Pants

This was a very quick and easy Friday night project. I’ve been trying to get ahead of a summer wardrobe and needed some lightweight pajama shorts.

Pattern Background

Jalie 3243 pull-on pants and shorts have front patch hip pockets, an elastic waistband, and the option of having either the waistband facing showing on the front (nice if you want to do a contrasting color) or hidden inside. This pattern is drafted for wovens.

Sizes go from 2T all the way up to women’s size 22. As is often the case with Jalie, I chose this pattern because the wide size range and classic styling mean I can use it for my toddler son as he grows as well as for myself and my husband.

Materials

You can use both regular and stretch wovens. I used a lightweight plaid flannel I bought back in 2012 from Fabric Mart. It isn’t the best quality flannel but since I wanted these for summer pajama shorts the light weight and minimal nap worked in my favor. (And yes I really paid only $3 a yard! How I miss the times before rampant inflation and tariffs.)

Size and Alterations

I cut a size CC based on my hip measurement. For alterations I added 2.5” to the center back seam height, tapering to nothing at the center front. I also added 1/4” width to the front inseam. I left the pockets off because these are for pajamas and I just didn’t want to deal with trying to pattern match that.

My first pair wasn’t uncomfortable but they just seemed too snug for my taste. Jalie does note on their website that if you want a looser fit in the hip you should go up a size or use a stretch fabrics.

I also noticed they were too tight in the butt and the side seam wasn’t hanging straight. So for my second version I added 1/4” to all side seams, thus giving myself another 1” of ease, and added another 1/2” width to the back side seam at the hip. Here’s what the back piece looked like after I was done:

These alterations made my second pair much better.

Construction

These pants are very quick to make. I sewed them on my Juki TL-2010Q (always a pleasure to sew on for light to medium weight fabrics) and finished the inside seams on my serger. I did a couple things slightly different from the instructions though.

Rather than creating a casing and then pulling the waistband elastic through, I sewed the seam allowance of the waistband facing piece directly on top of the elastic, overlapping the edge of the seam allowance about 1/4” from the left edge of the elastic and using a 4mm length stitch so I wouldn’t overwork the elastic and stretch it out of shape. Then after I rolled the elastic to the inside of the shorts I stitched very close to the lower edge of the elastic. Once it was done the elastic was completely encased and then I topstitched in the middle. No need to make a casing and then pull the elastic through.

Of course it isn’t as adjustable after the fact so probably not good for kids clothes or your first version, but good for situations where you have confidence that you won’t need to alter it after the fact.

When I did the hem I first turned it up only 1/4”, then turned it up again another 3/4” and stitched very close to the edge. Very similar to how I did the waistband. This made for a very neat hem finish:

In the past I used to serge then fold to the inside and then topstitch over the serged edge, but I find myself preferring to try new things and do finishes like this lately. Helps distract from some recent sadness like my father’s health struggles and losing my beloved cat recently. (My dad actually improved enough that he was able to go home to my mom a couple of weeks ago, but I’m still doing a significant amount of caregiving duties. And while my cat had some health struggles the past six months, I wasn’t anticipating losing him quite so soon and miss him terribly.)

Conclusion

This is a really nice pull on pants pattern for all ages. The waistband facing eliminates having to measure and turn up a waistband casing, and the fit is actually quite tailored for this style of pants. I do recommend going up a size though if you use a non-stretch woven.
