Section 03
Key Buying Factors
01
Fit
Look for activewear with a flattering yet functional fit. High-waisted leggings with tummy control and adjustable straps on bras ensure no slipping or digging.
02
Fabric
Moisture-wicking, breathable fabrics like nylon-spandex blends keep her cool and dry. Avoid cotton as it holds sweat and becomes heavy.
03
Quality
Check for reinforced seams, double stitching, and durable zippers. Quality activewear withstands frequent washes and intense activity without pilling or fading.
04
Style
Activewear should express personality. Bold prints, color-blocking, and mesh panels add flair while maintaining function. Let her choose what makes her feel fabulous.
Section 05
Care, Cost and Maintenance
Washing
Turn activewear inside out and wash in cold water on a gentle cycle. Avoid fabric softeners as they break down elastic fibers.
Drying
Air dry flat or hang dry away from direct sunlight. High heat damages elasticity and causes shrinkage.
Storage
Store folded to maintain shape. For bras, stack cups to avoid crushing. Keep away from velcro or rough fabrics that cause pilling.
Pro tip
Always have her try on activewear while doing a few squats and stretches to ensure it moves with her, not against her.
Frequently asked questions
What sizes are typically available in plus size girls' activewear?
Sizes often range from 1X to 3X, but some brands like Girlfriend Collective and Old Navy extend up to 6X. Always check the brand's size chart for specific measurements.
How can I prevent leggings from rolling down during activity?
Look for high-waisted styles with a wide, stretchy waistband. Some leggings have internal drawcords or silicone grippers for extra security.
Are there specific fabrics that are better for sensitive skin?
Yes, choose activewear made from bamboo, organic cotton blends, or seamless knits that minimize chafing. Avoid synthetic fabrics with rough seams.
Can plus size girls wear the same activewear for different sports?
