Girls’ Underwear

Your place for the annual underwear stock-up

Every year – and sometimes multiple times a year – the time comes to restock your kids’ underwear drawers. Whether they’ve grown out of their old undies (or some pairs just shouldn’t see the light of day again!) Zulily has the underthings for girls you need to get the situation back on track. 

OMG! Why are there so many types of underwear?

Underwear for girls comes in all shapes and sizes for little kids to big kids, and in all types of patterns and designs, so you can get pairs with their favorite Disney or Marvel characters on them or aim for something simpler.

Which underwear style is right for your kid?

Girls’ briefs are classic. Briefs have wider sides and a mid-rise to provide a good amount of coverage.

Bikini-style kids’ underwear is similar to a brief, but has a lower rise and slimmer coverage on their hips. These are more optimal for lower-rise pants and shorts.

Girls’ boyshorts underwear provides the most coverage and is often a great option if your kid is more active, since they will really stay in place.

Training pants can be disposable or washable. The washable kind typically feels like thick, comfy cotton underwear, but features an extra absorbent lining for leaks and oopsies. Washable training pants for girls make it so you can reuse them week to week, while also giving your kid the feel of real underwear. And with prints featuring some of their favorite characters, they’ll love to wear them, too.

Girls underwear sizing made easy

Make sure to check a brand’s size chart for kids’ underwear while you shop. If a pair of underpants is too small, it can pinch and rub, making your child uncomfortable and restricting their movement. If it’s too big, it won’t stay in place and will move around or bunch up. Most underwear is sized according to weight and waist measurement.
