Organic Cotton Underwear for Girls

Too often, girls' underwear is an afterthought. Overly tight, skimpy on coverage, or made with scratchy synthetics. Sometimes it's even designed to look... not quite like something for kids.

At Treehouse, we do it differently.

Designed with Her in Mind

• Full Coverage Comfort: Soft, breathable, and properly sized to give her room to move without wedgies or ride-ups.
• Stays in Place: No slipping, bunching, or digging in, just all-day comfort, no matter the activity.
• Soft, Gentle Elastic: Waist and leg bands that hold gently without pinching or leaving red marks.
• Hypoallergenic Fabric: GOTS-certified organic cotton that’s perfect for sensitive skin and free from harsh chemicals.
