What I love most is the excellent UV protection, giving me peace of mind while my little one plays outside. Not to mention, it's incredibly cute—my toddler loves wearing it!"

"I ordered this cute suit for my 2-year-old in a hurry, and I couldn't be happier. The strawberry design is adorable, and it stretches well for a comfortable fit. The snaps are sturdy, which is great for diaper changes. I'm relieved to see that it provides good sun protection—exactly what I needed!"

"I only buy Rufflebutts swimsuits because of the value and quality. I appreciate the snaps and zipper for convenience. The fabric is stretchy and soft, though the seersucker isn't as soft. Overall, these swimsuits have the best fit and are absolutely adorable!"

"After spending 5 hours at the lagoon, my fair-skinned baby had no sunburn thanks to this swimsuit. It's true to size—my baby, who's almost 6 months, fits perfectly in the 0-3 months size. I’m impressed!"

"This swimsuit is precious and made from good quality fabric. I encountered a minor issue with a snap breaking, but the customer service was impeccable and I received a replacement quickly. I would highly recommend this brand!"

"We desperately needed a sleeveless suit while at the beach, as my baby screeched when trying on one with sleeves. This suit is precious and caused no tears when dressing our 8-month-old. Just remember to size up!"

"I find this swimsuit absolutely adorable for my 4 1/2-year-old granddaughter. It has a great fit and I appreciate the adjustable pink shoulder straps!"

"The YOUNGER TREE Toddler Swimsuit in Color Block Stripe is a true delight! The vibrant colors and stylish design make my little one look adorable. The high-quality material is soft and comfortable, allowing her to play all day at the beach or pool without any issues. It holds up well to washes without fading. It provides good coverage and stays in place, allowing her to move freely. I highly recommend this swimsuit for its style and quality!"

"I found the cutest little bathing suit for my baby. The snap bottom makes changing her so easy, and I can't tell you how many compliments we've received on it!"

"I bought the 3-6 month size for my 5-month-old, and it fit her perfectly! It was not too tight and the colors remained bright after washing."

"We took this swimsuit on vacation, and it was a hit! The great lining made a big difference in quality. I definitely recommend going a size up since it does run small."

"I've tried many swim suits, and this one is by far the cutest and most stylish for the price! It’s super inexpensive for what you get. My baby is 6 months and has always been a little ahead in sizing; it fits her perfectly now, but I will definitely have to size up in the next month or two! The leopard with the pink is SO CUTE! She stood out in swim class, and I loved watching her explore the water! The material is amazing!"

"I think this is a cute product at a great price. They seem to run large, but not much bigger than what I expected. My daughter is a 3T – sometimes a 4T, and it’s a little big on her."

"We got this suit along with another for my infant, and they seem sturdy with cute color choices. They were a great deal and look and feel similar to more expensive brands!"

"I had a hard time finding a swimsuit small enough for my 9lb, 24in baby, but this one fits perfectly. It's easy to get on, and even when wet, it came off without a struggle! The high-quality material has held up beautifully after multiple washes, with no fading or deterioration. My baby seemed comfortable in it, and it’s just the cute swimsuit I was looking for!"

"This swimsuit is the cutest ever! My 3-month-old looked absolutely adorable in it! I was on the hunt for something to protect her fair skin, and this is by far the best option I found. I even bought a matching set for my older child. The back zipper is a fantastic feature, and it held up against the concrete at the splash pad with 10/10 durability. We received so many compliments!"

"I absolutely love this swimsuit! It fits my baby so well and the vibrant colors are striking. The material is thick and seems really comfortable. The snaps and zipper make it easy to get on and off, which is a huge plus for me!"

"I absolutely love the print and color of this swimsuit! My daughter seemed comfortable, though we did have to fold the sleeves a bit since they were a little long. The sun protection is a huge bonus, and the zipper at the neck along with the snaps on the bottom makes it super easy to put on and take off, especially when she’s wet."

"This suit was perfect for our newborn during our beach trip due to its UPF protection and long sleeves! We initially bought two suits, but this one quickly became her favorite because of the front zipper. The other suit’s back zipper kept sliding up, which was a hassle. We got a size 3-6 months for our 3-month-old, and it fit just right while providing great quality and coverage!"

"I think this is the cutest suit ever! It fits my 5-month-old perfectly, but I do wish there were buttons between the legs for easier diaper changes. Taking off a wet suit to change a diaper is quite the challenge. If I had noticed this before purchasing, I might have reconsidered, but now that I have it, I really love it."

"I was looking for swimsuits for my daughter, and these were perfect! We got two designs, and she was thrilled to wear them. They're adorable, vibrant, and comfortable. The adjustable straps are a huge plus! She looked like a little pro in her swim cap. Definitely size up; we bought 5T for her 3-4T size, and they fit perfectly!"

"I purchased this for my granddaughter, and I was really impressed by the fit. The adjustable shoulder straps are fantastic, and the colors are spot-on. I can easily spot her at the pool, which I love!"

"I bought the mermaid suit for my granddaughter, and she absolutely loved it! The bright colors and great fit made her feel like a real mermaid at the pool. I was happy with the price on Amazon, especially since it was off-season for swimwear in stores. I ended up buying the same suit again a few months later!"

"I bought this for my 12-month-old daughter who fits a 12-month clothes size, and the sizing was spot on. We took her on the boat, and she didn't get any sunburn. Of course, we applied baby sunscreen on her face and hands, but the swimsuit did a great job covering her body. I definitely recommend this for a fun day by the water!"

"The quality and appearance of this swimsuit are fantastic, and it offers great sun protection. It was truly worth the investment!"

"I wonder why the kid in the picture isn’t wearing the headband that comes with the swimsuit. Thankfully, the model is cute, but I found the background to be quite unpleasant."

"I found the suit to be lightweight and fast drying. The fit is snug and it's absolutely cute! I'm definitely using it again this summer since it comes in a good size range."

"I absolutely love the ruffles, color, and print! However, I did notice that the material is quite thin."

"The suit is very stylish and has a silky smooth feel. I did find a few threads hanging that I had to trim, but overall, the quality is amazing for the price!"
