Customers praised this adorable sewing pattern as "beginner friendly" with "easy to read" instructions and a "quick sew." The design works beautifully as both a swimsuit and romper. Fit runs true to size, though one customer found sizing large. Loved for its "cute" bubble design and elastic leg construction.
Seriously the CUTEST sunsuit, it makes the perfect halter when sewn up in yummy rib knit! It’s become a new favorite and the elastic leg was much easier than I expected. The instructions are super easy to read! Thank you!!
Fantastic pattern! Easy to read and put together! Ordering and downloading was very simple as well! Needed a custom print swim suit for my niece and this was absolutely perfect!
This is such an adorable pattern..I made one in cotton spandex as an outfit for my daughter and it looks soo cute on. It was a nice quick sew and the fit was great! I’ll definitely be making more.
Super amazing design. And so cute when finished. Instructions are clear and easy to understand. Perhaps easy enough for a beginner. But definitely recommend for a intermediate :) Love the bubble suit 😍🥳
In love with this style! I used DBP and it still came out so adorable can’t wait to make more! The instructions were very easy! Didn’t take long to put the pattern together! I’m excited to make more of this cute romper! Thank you lowland kids! Here’s my daughter Sofia wearing a 3T she’s normally a 4/5T I wanted a snug look! And it still fit perfect!
Beginner friendly and easy to hack into a romper by adding leg bands and using knit.
This suit is the cutest! It also doubles as the cutest romper! I'm totally in love!
I loved the look of this little romper style swimsuit for my 1.5 year old. It was a quick, easy sew and I think I’ll do another couple up in different bases for the summer time. My only issue was I picked her size based on measurements and it came out way too big. I had to detach and refinish with much shorter elastics to make it work.
I absolutely LOVE this pattern! Such a fun and quick sew. The instructions were easy to read and the pattern seems to run really true to size.
I love this bubble sunsuit pattern and it holds up really well at the pool. Very simple to sew for a swim pattern, and a very cute design.
This suit is perfect for beginners and masters alike. Simple enough for someone who has never sewn swim and it comes out looking amazing! A definite must for any summer wardrobe
It took me about an hour from cut to finish for this adorable little suit. It's also super comfy, as my daughter didn't want to take it off after trying it on! Perfect fit. We can't wait for warmer weather to show it off!
I love this suit! It was a quick sew and super easy to get on and off my wiggly 2 year old. Would recommend :)
The pattern is very beginner friendly and quick and easy. my daughter loves her sunsuit!
I love this pattern. Instruction was really easy to understand and swimming suit was quick to sew. My 2 years old girl dont want to take this away from her.
I just love this pattern!! It’s so cute & such a quick sew. Love that there is an option for a snap too. I think I’m going to need to make about 100 more for my daughter!
This pattern is going to be our go to this summer. It was very simple and such a quick sew. It's incredibly adorable and looks so comfortable. My girl doesn't want to take hers off!
Chic and cute. And the pattern is easy to follow. A summer wardrobe must-have for babies for sure. :heart_eyes:
This was my first swimsuit I've ever sewn and I was so pleased with how easy it was! Everything came together and fits perfectly. My toddler loves it so much she wears it in the bath every day! Haha
Such a cute quick sew great instructions as well!! I love that I can also make it with CL and turn it into a daily outfit!!!
Absolutely LOVE this sweet bubble romper swimsuit! It was my first time sewing with swim and it came together so easily! Another win for Lowland Kids!
This suit is exactly what I was looking for! Super adorable, trendy, and a fast sew! Love, love love!
