Bathing Suit Bottom Redo

One of my recent sewing projects has been to replace the worn out elastic in some bathing suit bottoms.  To be honest with you they were wore out last year but I neglected to fix them then.  I decided I needed to get them done this year as I really like the bathing suit and the top was still in good shape – so are the bottoms except for the elastic.

Ripping elastic from bathing suit bottoms

The above photo is of the bottoms with 2/3 of the elastic removed.  Let me tell you that removing the topstitching and then the serged edge that attaches the elastic is a lot of work!  I think it probably took me 3 or 4 hours total time (I didn’t do it all at once, it was too boring) to rip all of it out.

Once I had the elastic all removed the process was a lot faster and only took about 20 or 30 minutes to put in the new elastic.  I used a Kwik Sew pattern, pattern 3238 which is a bathing suit pattern I have made before, for the elastic length for the waistband and the legs.  I knew that those bottoms fit me well and the elastic measurements would be right.

Sewing elastic to bathing suit with serger

After cutting the elastic to the measurements I used my serger to attach it to the edges of the waistband and leg openings.  I first divided the elastic in half and then divided the bottoms fabric in half and marked it so I would know where and how much to stretch the elastic as I sewed.  I also used wooly nylon thread in the lower looper as that part will be next to my skin and the wooly nylon is a lot softer and provides a lot more coverage and stretch than a regular polyester or cotton thread.

Sewing elastic down with sewing machine and narrow zigzag stitch

After attaching the elastic with the serger I then took it to my regular sewing machine and turned the elastic over and stitched it down using a narrow zigzag stitch of a 2 width and a 2 length to topstitch the elastic in place.  I also used a ballpoint needle as it sews knits and over elastic better than a universal needle.

The photo above is of the front and back of the bottoms after replacing the elastic.  I even remembered to sew the tag back in the back – not that I couldn’t figure out which was the back but I was glad I remembered.

Bathing Suit with elastic replaced in bottoms

 

Well, here is my new-old bathing suit.  I tried the bottoms on and they fit much better now and are not all loose.  It took a while (like a few weeks) for me to complete this project as it was a real pain to rip out that old disintegrating elastic.   It was so bad it would just crumble in some spots but I still had to rip out all of the old serging holding it in so I could replace it and not have all of the bulk.  The top for some reason does not, and I hope won’t any time soon, have this same problem and as you can see the bathing suit is still in pretty good shape for being several years old.  I am glad I was able to recycle it and not have to just get rid of it.

The weather here is still hot and will be for at least another month or more so I will be able to wear my “new” bathing suit when we swim in our pool.  My advice to anyone attempting to do an elastic replacement in a bathing suit is to be patient and just keep at the ripping of the stitches and eventually when you get to the sewing part it is super fast and easy.

Have a great day!

    Great job, and thanks for the tutorial.

    Have you ever had elastic melt into an old bathing suit? I cannot figure out how to fix it because I love the suit, but I cannot figure out a way to remove the elastic. Such a pain, it was a cute suit. I keep trying to find another person (on the internet) with this issue.

      Lorna – I am wondering if you could cut it out – although that would reduce the amount of fabric there. Have you tried soaking it in ice cold water and then maybe it would be brittle enough to rip out. The elastic in this suit was pretty brittle in some spots and just kind of crumbled out. I still had to rip out all the serger stitching though. Thanks for stopping by – good luck with your suit.

      Thanks! It is not too complicated it you are familiar with sewing with knits or stretchy fabrics and elastic. The most annoying part is getting the old elastic out! Thanks for stopping by!
