Key Buying Factors
01
Fit & Comfort
Look for adjustable ties, elastic leg openings, and stretchable fabrics that move with baby's kicks and wiggles without riding up.
02
Fabric & Sun Protection
Prioritize UPF 50+ fabrics that block 98% of UV rays. Quick-dry materials like nylon-spandex blends reduce chlorine absorption and keep baby comfortable.
03
Quality & Durability
Reinforced seams, rust-resistant zippers, and colorfast dyes ensure the suit survives sandy washes and multiple wears. Check for double-stitching at stress points.
04
Style & Function
Fun prints, ruffles, or character themes add charm, but features like full-zip rashguards or snap closures for diaper changes are equally important.
Section 05
Care, Cost and Maintenance
Rinse After Use
Always rinse swimwear in cold fresh water immediately after swimming to remove chlorine, salt, and sand.
Gentle Wash
Hand wash with mild soap; avoid bleach or fabric softeners that break down elastic fibers.
Flat Dry, No Wring
Lay flat in shade to dry; never twist or wring out water, and keep away from direct sunlight which fades colors.
Pro tip
For extra sun safety, layer a long-sleeve rashguard over a swim diaper and finish with a wide-brim sun hat. Bonus: it makes diaper changes a breeze.
Frequently asked questions
How do I choose the right size for my baby's swimsuit?
Measure baby's chest, waist, and inseam; compare with the brand's size chart. For a trim fit, choose the size matching weight or age, but if baby is between sizes, size up for room to grow.
What fabric is best for baby swimwear?
Look for UPF 50+ rated fabrics with a blend of nylon and spandex (or polyester-spandex). These offer stretch, quick drying, and durability against chlorine and sun.
Can I use regular sunscreen under swimwear?
Yes, apply a broad-spectrum SPF 30+ sunscreen to any exposed skin 15 minutes before sun exposure. UPF swimwear covers the rest; don't forget ears, feet, and back of neck.
How often should I replace baby's swimsuit?
If the fabric has stretched, faded, or lost elasticity, it's time for a new one. Baby's growth spurts may necessitate a new size every season.
