Best Tankini Sets for Girls of 2025

"I bought this suit for my very tall and slender 5-year-old, and it fits her perfectly! The top covers her belly, and the bottoms provide great back coverage. The straps stay on well, and she's really comfortable in it. It's ideal for camp mornings with shorts over it, making bathroom trips easy. The fabric feels well made, and I love it so much that I bought it in five colors!"

"My 6-year-old loves swimming in this suit! We originally bought a different color last year and were so pleased that I purchased two new ones for this season. The fit is excellent, it stays in place, and because it's a two-piece, it's perfect for quick potty breaks. After using it all summer in the pool and at the beach, there's hardly any wear. Unlike other brands we've tried, this one has held up beautifully!"

"I got these suits for my two daughters, ages 6 and 8. They are adorable, but I've noticed that after just a month and a few washes, they seem to be riding up more than before. I love the designs, but I feel they run small. Next time, I will definitely size up when I buy again!"

"This swimsuit is so cute! It was a little big for me since I'm tall and lean, but overall, I find it adorable. It covers my stomach completely, though I think I should have sized down for the top."

"I'm really pleased with this great quality swimsuit for my daughter. She absolutely loves the rainbow colors and it fits her perfectly. We've been using it all summer without any issues like fading or stretching!"

"I got this swimsuit for my little girl, and I'm thrilled with it. The material is good and it dries quickly. I appreciate that it's easy for her to use the bathroom with the two-piece design, and it offers enough coverage to protect her from the sun—just remember the sunscreen!"

"I find this set adorably cute and it fits my slim/tall 10-year-old perfectly!"

"The shorts and tank provide great coverage and they’re not bulky, making it easy for my child to play."

"I found the top too tight for my 10-year-old, but the bottoms fit perfectly. It’s a really cute swimsuit and the quality is great!"

"I ordered a size 12 for my daughter, but it was too small. After returning, the size 14 fits well and the coverage is good!"

"The colors are vibrant and the suit runs true to size for my daughter. However, I wish it had a built-in bra."

"This bathing suit fits my 10-year-old perfectly! It's both cute and comfortable."

"My daughter adores this bathing suit! The bold red color and the cool back straps are a hit. It's a flattering suit, although the bottoms are a bit oddly shaped for her slender frame."

"I had high hopes for this swimsuit, but it was way too small for my stick-thin daughter. I recommend sizing up by at least two sizes."

"I originally received the blue suit, but it was too small. I returned it and got a refund quickly, then ordered the next size up in purple. Still super cute and fits just right! I've been swimming and going to the beach, and it looks brand new!"

"In the past, I bought swimsuits for my daughter that didn't last long at all. This is our second Speedo suit, and like the previous one, it holds up really well. Daily swim use, drip dry, and it retains its color and shape perfectly. I highly recommend Speedo swim suits for kids!"

"My child usually wears sizes 8 or 10 at 7.5 years old. We started with a size 10, but it was way too small, so we got a size 12 that fits nicely. This suit is well-made and holds up to swim lessons and other outings, which is why I chose Speedo."

"I ordered three sets for my daughter, who is 6 and a bit thicker. We got the patriotic, sporty, and rainbow mermaid scale sets. The sizes were just right; the smaller ones fit perfectly, while the 9-10 is a bit roomier but still wearable this year. The material quality is fantastic—thick and well-made, with vibrant colors. It's easy for her to put on herself and offers good coverage. As a budget-conscious mom, I highly recommend these suits!"

"I purchased the 11-12 size and found it true to size. The coverage is excellent for my curvy daughter, and the color has remained vibrant after several washes this summer. I'm pleased with the overall quality and fit!"

"The tankini top and skirt fit me perfectly, though the bottoms were a bit big. Thankfully, I have other swim bottoms that match well. Overall, I'm happy with the nice quality fabric and the good price point!"

"I absolutely LOVE this bathing suit! My daughter has been fascinated by the stars and nature since she was little, and this style is perfect for her as she grows. It fits her wonderfully, and she wears it every time she goes to the pool or beach!"

"My daughter, who's 10, has been wearing this suit all summer. It's adorable yet not too childish for her '10 going on 20' mindset. We've paired it with black swim shorts for extra coverage, and she feels comfortable and confident around her friends!"

"This swim dress is just adorable! My little one loves it and can wear it without a cover-up, making it look like a dress. Just a heads up, it does run small, so I recommend sizing up by at least two sizes."

"I found this suit very easy to put on, and it looks just as vibrant as in the ad. It's also perfectly age-appropriate for my 10-year-old. After a few washes, it remains flexible and durable."

"I purchased this swimsuit for my granddaughter, and I decided to buy it two sizes bigger. It fits a bit large, but it's manageable, and I believe she can wear it next summer too. The color is lovely, and the quality is impressive. I would definitely recommend it."

"I ordered the pink swimsuit, but when it got wet, the color bled a lot. After my daughter used it in the bath, the water turned pink! The black and purple versions are fine, though. Overall, it fits true to size and is good quality."

“I bought this for my daughter, and she absolutely loves it! It's adorable and fits her perfectly, allowing her to feel comfortable all day. The quality is fantastic, and it's holding up really well.”

“I purchased this for my stepdaughter, who is 8.5 years old and weighs 118lbs. I got her sizes 12-13 and 15, and the size 15 fit the best. It's a really nice bathing suit made of excellent material, so I think it’s definitely worth the investment!”

“My kiddo is thrilled with the option of short bottoms instead of just bikini bottoms. She adores the rainbow space flamingo print! Usually, she wears a size 10, and the size 10 fits her perfectly.”
