Tank Romper

$8.00
 

The tank romper is simple sweet summer staple. The fit is semi loose in the body. It comes with the options of big pockets, pull on through the top or buttons/snaps up the middle, crotch snap, and pant or short options! You can swap out the binding for bands if you prefer (though it will change the width of the tank slightly).

I hope you enjoy this amazing closet staple!

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.

Cute Romper

This is just what I was looking for in a children's romper, the instructions are easy to follow. I made a few changes for my own personal preference. I prefer to sew the arm bands in the round so there is less bulk at the seam. When I make a very small size, I hem the legs before sewing up the side seam, I might try a small cuff next time just to see how it looks.

Just the best Tank Romper

I loved it! Such an easy project. The measurements are perfect, I made 18-24 size, and it was precisely the size. The Style- at the beginning, I wasn’t that sure, but the big pockets were sewed with the side seams giving it a unique look.

Cute, easy make

Super cute! Only issue I ever have is with the way you add the crotch snap plackets; those aren't quite durable or large enough of a placket for me.

Great pattern and nice it

Great pattern and nice it was available in different formats. Good explanation of how to print and select sizes (cool layer feature in Adobe). As I'm new to sewing with knit fabrics this was challenging, it would have been helpful to have some links to resources or tips for knits. Very cute outfit overall!

Tank Romper

Pattern was super easy to sew. Measured true to size for my little one depending on fabric type. Made with French Terry it fit perfectly but when made with waffle it was nicely oversized due to fabric recovery. Instructions were easy to follow. 10/10 for this pattern I made two in under a week for my little man to wear all summer!

Missing Pattern Piece

No binding piece for the snap crotch. And the instructions of just folding over the raw edge there could use some work.

The projector version doesn’t have

The projector version doesn’t have labels on the leg, arm, and neck bands…I had to flip back and for to figure it out. The neck band says cut one with no fold but was not long enough for the whole neck. Also disappointed there’s no measurements for the snap placket on the bottom panel. Instructions don’t even discuss how to come up with the right measurements for this. I used the size 3t projector layer

Tank Romper

Tank romper was an easy pattern and a quick sew. My little one loved the pockets as well! Will be making more of these. Only thing I wish, was that there were band instructions. Other than that, everything cane out great.

Good but needs more details

I love the fit and style of the romper but, I wish the instructions were more detailed. When it came time for binding in the instructions, it just said to add it but did not show how.
