What kind of underwear is best for tweens and teens?

It depends on the day, which is why our collection covers both: soft cotton underwear for everyday comfort and breathability, and seamless underwear that disappears under leggings, dresses, and activewear. Most girls end up with a mix — cotton for school and sleep, seamless for sports and outfits where lines show. Every pair is tagless, made to stay put, and designed for growing bodies.

How is underwear for girls different from women's underwear?

Cut and proportion, mostly. Girls' underwear is designed for growing bodies — higher-cut rises that stay put, softer waistbands that don't dig, and no scratchy lace or embellishments. Sizing runs on a girls' scale rather than women's, so a great fit doesn't require sizing way down in adult styles that were never shaped for her.

How do I find her size?

Every product page has a size chart mapping sizes to age and waist/hip measurements. When she's between sizes, we suggest sizing up — underwear should never leave marks on her skin at the end of the day. If it does, it's too small, no matter what the tag says.

How many pairs does she actually need?

A practical wardrobe is 8–10 pairs in rotation — enough for a full week plus sports and sleepovers without laundry emergencies. That's why our underwear comes in bundles: mixed colors, one size, better price, done in one order.

What about sensitive skin?

This is where fabric choice matters most. Our cotton styles are all-natural and breathable — the gentlest option for easily irritated skin — and every Yellowberry pair is tagless with soft, flat seams. If scratchy waistbands or tags have been a battle, cotton bundles are the place to start.
