Key Takeaways There are 11 main types of underwear for women, and they differ mostly in how much they cover and where they sit on your waist. Your butt shape can guide your pick: round and heart shapes suit minimal styles, while square and inverted shapes suit briefs, mid-rise, and high-leg cuts. Wear seamless or minimal styles under fitted outfits, and match your underwear’s rise to your pants’ rise for everything else.
