Look for firm elastic:
No one wants to be pulling at their underwear all day to keep it from slipping or falling. Choose the panties with firm elastic in the waistband, so you know they will stay in place.

Avoid underwear that's too tight:
Panties that are too tight lead to bulges and lumps beneath your clothing. They may cause skin chafing and irritation due to friction as well. Any brief that's tight enough to leave marks on your skin is too tight. Tight briefs don’t breathe as well and can lead to health issues and leave you a little sweaty.
