The fastest way to ruin good activewear is the dryer. The second fastest is fabric softener. If you want girls activewear to last past the next growth spurt, the care routine matters as much as the fabric quality. Here is exactly what to do, and why each step makes a difference.
Cold Wash, Inside Out, Every Time
Hot water breaks down elastane. That is the fibre giving performance stretch its 4-way movement and its ability to bounce back after a session. Once elastane degrades, the fabric loses recovery and leggings sag at the knees after just a few washes. Cold wash at 30 degrees or lower protects that stretch. It also protects printed details, colour vibrancy, and any mesh or lace panels.
Turning garments inside out before washing does two things. It protects the outer surface from friction against other clothes. It also gets the sweat-contact side, the side that actually needs cleaning, closest to the water and detergent. Both results matter for longevity.

What to Avoid and Why
Skip the Fabric Softener
Fabric softener coats fibres with a waxy residue. On activewear, that coating blocks the moisture-wicking channels built into the fabric. After a few washes with softener, a leotard or pair of tights that was designed to pull sweat away from the skin stops doing that job. The garment still looks fine, but its performance function is gone. Use a small amount of gentle liquid detergent instead, one without brighteners or bleaching agents.
Avoid the Dryer Completely
Heat is the enemy of elastane, lycra, and any bonded seam construction. Even a low dryer setting shortens the life of activewear significantly. Hang garments to dry in the shade. Direct sunlight can fade colour over time, particularly on darker tones and printed designs. Flat drying on a rack works well for heavier pieces that might stretch under their own weight when hung.
Mesh Bags for Delicate Pieces
Mesh laundry bags are worth keeping in the laundry cupboard if you wash dance tights, mesh overlays, or any garment with embellishments. They reduce the friction and snagging that damages delicate constructions during the wash cycle. Zip up any velcro on other items in the same load too, since velcro catches on fine knit fabrics.
How to Wash Girls Activewear After Sweaty Sessions
Sweat contains salts and oils that break down fibres if left sitting. If a garment cannot be washed immediately after a session, take it out of the dance bag and let it air rather than leaving it damp and bunched up. Damp fabric in an enclosed bag is where odour sets in, and once that happens it is very difficult to remove fully.
For sessions where odour is a concern, a short soak in cold water with a small amount of white vinegar before washing can help. Rinse thoroughly and then wash as normal. This works particularly well for nylon-based fabrics.
Understanding what fabric your daughter is wearing also helps you care for it correctly. Our guide on choosing the right activewear for dance, gym and sports covers fabric types in detail so you know what you are working with before it goes in the wash.
Sizing, Washing, and Making It All Last Longer
Good care habits extend the life of activewear, but sizing plays a role too. A garment that is pulled too tight across the hips or shoulders is under constant stress at the seams, and washing compounds that stress. Buying with a little growing room and then caring for the garment properly is the most practical approach for active kids who are still growing.
If you are navigating sizing across brands and growth spurts, our article on sizing girls activewear during fast growth phases gives practical guidance on how to measure and when to size up.
It is also worth considering the fabric composition when making purchasing decisions in the first place. Some materials are far more durable through repeated washing than others.

A Quick Reference Wash Checklist
- Cold wash at 30 degrees or lower
- Turn garments inside out before washing
- Use a gentle liquid detergent, no fabric softener
- Place delicate pieces in a mesh laundry bag
- Air dry in the shade, flat or hung depending on weight
- Never use the dryer, even on a low setting
- Air out garments immediately after use if washing is not possible straight away
These habits add up. A well-cared-for piece of activewear can last through multiple growth spurts, which means fewer replacements and better value from quality fabrics. Shop our girls activewear for dance, gym and sports to find pieces built to hold up through both the sessions and the wash cycle.
