Rashguard Swimsuit
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.

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!
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!
Cute swimsuit i love it
Did a reversible version bc the kid didn’t want elastic. Still fit her. Always love the way instructions are written and worded.

Such a cute pattern and a wider neck makes for easier on and off. Easy to sew up and true to size. Love it!
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.

I loved this pattern!! It is easy to follow and turned out so cute on baby rose <3
This swim suit is so cute when it’s all done!
Swimsuit is really cute and fits well. Elastic around the legs will become easier with practice. Plan to make another one soon.
This pattern is gorgeous. Super fast sew and my girl is covered from the sun and looks super cute.
Have not finished it yet, but so far so good. Tried it on my granddaughter and think it will fit perfectly for next summer.
I can’t even knock off a star for the fact that I am having to remake this in a 4T for the kiddo who is a 2T growing into 3T. I mad the 3T thinking it would be big but poor kiddo could not deal with the “wedgie in my butt”! It was really tight all over, but especially in her lower half, especially back rise.
Okay, that out of the way, this suit is so easy to sew up, especially with the help of The YouTuber “Come Create with Kim” (thank you Kim, so so so much). And, it looks so cool with the keyhole in the back with the ties. The flutters are fun and way easier then they look. I think that’s kinda the theme of this suit and a lot of Lowland patterns, it’s is really cool looking and maybe seems intimidating but is so doable and fun. I have never done drop in raglan sleeves before and I LOVE that way of installing sleeves now! And then, even if you don’t do a perfect job, you get this really cut, wonderfully functional, swimsuit that looks awesome. If you have a sewing machine and it have a zigzag stitch and you consider yourself a beginner, you can make this!
Love everything about this suit!
Amazing sew! Thank you for easy to follow instructions, and the finished product looks high end!
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.
This pattern came together so much faster than I imagined and has such a professional finish. There isn’t too much binding, which is nice and it would double and a super cute leotard pattern!
Instructions were very clear. A quick and fairly easy sew. Lowland kids is definitely my first pick for kids patterns. On point :ok_hand::skin-tone-2: Fit good to size too
This pattern is perfect for baby swimwear. It was easy to put together and fit perfectly when using size that matched measurements. My first time sewing with swim fabric and I'll be making more!
Very good instructions that make it easy to sew. Lovely pattern
Super easy sew! Love this pattern
Instructions are clear and easy to follow. Size fit my daughter well. The pattern is awesome :sunglasses:
I love this suit! Made out of DBP as a test before trying on swim fabric, and it is a hit with my 5 year old. Love the sun protection the long sleeves offer. I will definitely be making more of these.
I had been previously hacking another pattern to make a rashguard. The fit is so great on this for my little guy! I love it 🥰
A sweet rashguard with a beautiful fit!
The rash guard is such a quick and easy sew! Although a fabulous pattern for all levels, it’s particularly a great one for a beginner. The instructions are very clear and easy to follow. This is a versatile pattern, great not only for swim, but also for layering in cold weather. A must-buy!
I love this pattern! I’ve made the rash guard for my son and he already needs a million more! Such an easy sew! Thank you!
I made the rash guard and it was so quick and easy! It’s so comfy that my girl didn’t want to take it off when she tried it on!! I’m so excited to do the full suit for a leotard too!!
The fit is awesome, such an easy sew and it works great as a leo or an underlayer shirt too if you use Jersey knit.
This was my first swimsuit and I'm so happy I tried this pattern! It was so easy and it came out as a great fitting suit. My daughter didn't want to take it off. Excited to make another for my other kid! 5 stars!
Beautiful suit, exactly what my little needed to be protected for the swim season! Quick sew, great instructions!
