"As someone who swims laps regularly, I love how this suit stays in place and feels supportive without being too tight. The fabric is high quality, and the color remains vivid after many swims and washes. I would definitely recommend it to anyone searching for a dependable and stylish swimsuit."

"Finding the right fit for my petite 9-year-old has always been a challenge, but the Speedo suit in size 10 is just right—not too wide in the hips and with room for movement. The pattern is even more vibrant in person, and the soft, well-made fabric is a big plus. Great choice for kids with a similar build!"

"I've always loved these swimsuits for my daughter—the quality is top-notch, and the fit is perfect. The coverage gives me peace of mind, especially since it doesn't ride up. The vibrant colors last wash after wash, and I appreciate that it's designed for comfort and durability."

"We've been fans of Ruffle Butts since toddlerhood, and this suit is no exception. It’s well-made, stylish, and provides great sun coverage.

"I’m so glad I found this swimsuit in my daughter’s size on Amazon after missing out on the website. The quality is outstanding, and the fit is just right for her in-between size. She absolutely loves the cute, modest style, and I appreciate that it pairs perfectly with her navy rash guard."

"This suit fit my tall, slim 12-year-old well, and she loves the padding in the chest. The only thing I noticed was the bikini area is a bit narrower than some other one-pieces, but it wasn’t a big issue. Quality is great and I’d just consider sizing up if you’re unsure."

"I picked this swimsuit as a backup, but it ended up being my daughter’s absolute favorite.

I’m planning to buy another in a different print because the price is fantastic!"
