"The rashguard swimsuit fits absolutely perfectly!! And was so easy to sew, took about 30 minutes from start to finish for the top. Definitely recommend. For the one piece version there is an awesome video tutorial!"
Rashguard Swimsuit
$9.00
This one is for the swimsuit sleeve lovers!
The pattern includes the option of a one piece Rashguard Swimsuit lined with a keyhole and tie back so it’s easy to get on and off. There is also an unlined regular rash guard option (which you can still add the keyhole if you’d like but you’d need to add liner or bind the hole). On sizes NB — 2T you can also add a snap placket at the crotch for easy diaper changes if desired.
Please note that with a tie on the back, it can be a choking hazard. Please do not leave your child unattended while wearing a garment like this.

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.

Beautiful pattern!
"Perfect pattern, super easy to sew! I loved the result 🥰"
A great pattern with a great fit but the instructions could do with some improvements
"Such a great pattern! I love that it has sleeves and the fit and length of them was great. The size chart was good, my daughter is 14months but wears 18months clothing, so I made size 18-24 and it fit her really well, a little on the tighter side perhaps, I don’t think she will be able to have it after the summer. The instructions were clear enough however I would have liked information about which stitch to use when sewing, for example zigzag 3mm long and 2mm wide for side seams. It helps a lot when using a normal sewing machine to sew. The neck binding I found a little tricky to follow too so I just didn’t my own version that worked. I love that you’ve added snaps at the bottom as an option, maybe specify that they should be plastic snaps. I assume metal ones will rust when in water. One last thing, there were two neck binding pattern pieces in the file. I assume the smaller one was for the top. I think this needs to be clearer in the instructions. Sorry for all the pointers, I really do love this pattern though and I plan on making many many more!"
Love!!
"I loved this pattern!! It is easy to follow and turned out so cute on baby rose <3"
Swimsuit is really cute and
"Swimsuit is really cute and fits well. Elastic around the legs will become easier with practice. Plan to make another one soon."
Great suit!
"This pattern is gorgeous. Super fast sew and my girl is covered from the sun and looks super cute."
So Cute!
"Such a cute pattern and a wider neck makes for easier on and off. Easy to sew up and true to size. Love it!"
Great for both boys & girls
"I love this pattern! So far I've made the rashguard for my son and it was a perfect fit! I have the swimsuit pattern ready to sew up for my 2 daughter's."
Rashguard suit
"Amazing sew! Thank you for easy to follow instructions, and the finished product looks high end!"
Love the rashguard.
"Thank you so much for your wonderful patterns. The fit of this rashguard is amazing and my girls are fighting over who gets the next one. This is love. My biggest sadness is that we are at the higher range of sizes. Just cut 2 more."
