For the perfect fit, don’t take a wild guess — take your hip
measurement! Standing with your feet together, wrap a soft
measuring tape around the widest part of your lower hip.

The fabric for our BASE undies is designed to have a snug fit
that moves with you. If you're between sizes, we recommend
trying the larger size for BASE.
No, our Everyday underwear are not leakproof or absorbent. These are basic undies to be worn any day of the month - add an Aisle pad or liner for period days, or check out our BOOST Period Underwear for leakproof period protection.
Since there is no leakproof panel in our Everyday undies, you may find that they fit slightly higher on the waist when compared to our BOOST period underwear. Otherwise the fit is similar. If you are between sizes, we recommend sizing down.
Take your hip measurement! Wrap a measuring tape around the widest part of your hips and bum, then choose the size that matches from our size chart. If you're between sizes, we recommend sizing down.
Just wrap the wings of the pad around the separated panel and snap underneath.
