Reversible Swim Bottoms

$8.00
 

These reversible swim bottoms are not only adorable, they are super easy and fast to sew (like 10-15 minutes from cut to finish once you've gone through the process). This pattern comes with regular and high waisted options. Sizes NB - 2T have a diaper and non diaper option.

This pattern has negative ease so you don’t NEED elastic though it doesn’t hurt to add a little in if you’re worried about stability and wear over time. Please make sure to measure your child before selecting your size!

If you are sewing to sell, I suggest adding elastic though it's totally up to you.

A quick note before you dive in: Our patterns include multiple files so you can sew the way you like—at home on a printer, at a copyshop (A0), or with a projector.

Quick answers

  • After checkout, you can download your pattern from the confirmation page, from the email we send, or anytime under Account → My Downloads using the same email you purchased with.
  • Your files come in a .zip. It’s easiest to download on a computer, unzip, and you’ll see: Instructions, Letter/A4, A0, and a Projector file.
  • Printing at home? Open the Letter/A4 PDF in Adobe Acrobat Reader and print at 100% (Actual Size), then check the test square.
  • Prefer no paper? Use the Projector file. It includes a calibration layer so you can confirm scale before you cut.
  • Need a big print? Send the A0 file to a local copyshop or an online printer.
  • If you get stuck, email hello@lowlandkids.com and we'll be happy to help!


Downloads & accounts


How do I get my files?
Right after payment you’ll see a download button on the confirmation page. We also email you links in your order confirmation email. And you can log in to our website any time and find everything under View Downloads.

What pattern files are included?
Four PDFs: Instructions, Letter/A4 (home printing), A0 (copyshop), and Projector.

Can I download on my phone or tablet?
Yes! Check out our Printing and Projector tips page for specific guidance.


Projector sewing (quick start)


Do your patterns include projector files?
Yes—our current catalog includes projector-optimized files for nearly all patterns. You’ll see “Projector” listed in each download.

How do I check scale?
Open the Projector file and turn on the calibration layer. Confirm the 1” / 2.5 cm squares measure correctly. If you move your projector or cutting surface, re-check before you cut.

Any setup tips?
Keep the text/markers layer visible. If labels look faint, check your PDF viewer’s accessibility settings and disable “replace document colors.” You can also enable the black background layer for higher contrast.


Print-at-home (Letter/A4)

1. Open the Letter/A4 PDF in Adobe Acrobat Reader.
2. In the print dialog, choose Actual Size (100%) and auto portrait/landscape.
3. Print the page with the test square first; measure to confirm scale.

Troubleshooting:
  • If the whole pattern prints on a single page, you likely opened the wrong file (use Letter/A4, not A0 or Projector).
  • If lines look fuzzy or misaligned, try “Print as image,” make sure your printer driver is up to date, and restart your computer.


Copyshop / A0

Download the A0 file and send it to a copyshop or an online service. Many sewists print a single master copy and trace sizes as needed.

Note that we protect our patterns by locking the pdf files to prevent editing in tools like Adobe Illustrator. In rare circumstances copy shops might use software that invisibly requests edit access and will show errors when attempting to open our files. 


Layers (print only the sizes you need)

All patterns include layers. Open the Layers panel in Acrobat Reader and hide sizes you don’t need. This keeps lines clear and makes grading between sizes easier.


Sizing & skill level

Each product page shows the skill level and links to the size chart. If measurements land between sizes, it’s common to use the width of one size and the length of another.


What machines do I need?

A regular sewing machine is all you need to start. A serger is optional but great for knit fabrics and tidy seams. A coverstitch is helpful for professional hems but not required.


Can I sell what I make?

Yes—items must be sewn by you personally. Mass production or outsourcing isn’t allowed. For manufacturing inquiries, email us.


Need help?

We’re happy to troubleshoot downloads, printing, or projector setup. Email hello@lowlandkids.com and include your order email and a screenshot of your issue if you can.
 

Customers said this sewing pattern is "quick and easy" with "perfect instructions." The reversible design is adorable and fits well when properly sized. However, some noted sizing runs small, requiring sizing up 2-3 sizes. Praised for no elastic option, beginner-friendly instructions, and fast completion time under an hour.

Fantastic pattern!

Really easy and quick to sew. I made the high waist and long top for my 3 year old granddaughter. She absolutely loves her new swim suit and it fits her perfectly. The instructions are perfect. Nothing but positivity to say. I’m sure I’ll be making another one soon. It’s a great way to use left over small pieces of swim suit fabric.

This is a very cute pattern but it runs TINY. I had to size up 2 sizes and honestly could go up 3. It makes it very hard to use for items for sale because the sizing is so off. Hopefully they'll revise it to be more accurate.

Stoked

Quite possibly the cutest thing I have ever sewn! My girls looked great in them, and I LOVE the honest instructions like "this bit will feel weird" or "trust me you need to do this" on bits I would have probably just tried to skip and regret later! I found it very hard to find perfect and easy to sew swimmers, so was stoked with this reversable swimmers

I found the sizing to

I found the sizing to be on the slim side through the hips. I made my daughter two size delta difference and she’s usually my RTW sized kid. And my friends daughter measured RTW the same size top to bottom and she has a hard time keeping on RTW clothing. That being said, the pattern is incredible, the instructions are thorough and I enjoyed sewing these and will continue to sew many many more. My only sad part is that one of my girls has almost sized out.
