This mermaid bikini set is absolutely adorable for your little beach lover! The rainbow mermaid print is so vibrant and fun, with shiny details that catch the light beautifully in the water. The 82% polyamide and 18% elastane fabric provides the perfect amount of stretch for active kids while maintaining its shape swim after swim. What's really impressive is the UPF 50+ sun protection that blocks 95% of harmful UVA and UVB rays - way better than constantly reapplying sunscreen on squirmy kids! The halter top style is super cute and adjustable, with a sweet bow knot detail on the back that adds that extra special touch. The fabric is quick-drying, chlorine-resistant, and salt-resistant, so it holds up perfectly whether you're in the pool, ocean, or water park. The double-stitched edges and fine front lining ensure durability and comfort, with full coverage that stays in place during all the swimming and playing. Perfect for swimming lessons, beach vacations, pool parties, or any summer water activities. The quality is immediately noticeable - this isn't that thin, see-through swimsuit material that loses its shape after one season. If your daughter is obsessed with mermaids or just loves colorful swimwear, this bikini set will quickly become her favorite for all water adventures. The size 10 fits most 10-year-olds perfectly, but definitely check the measurements to ensure the best fit for your growing girl!
