Anyway, the best way to get horizontal creases at the bottom of your booty is to grow your booty. I used to not have ANY crease, flat as a pancake. My butt just ran into my legs Grow the booty & the creases will come. The vertical line (your butt crack) will get a little longer too. Thank god, because mine is pretty short.

But something that's a quick fix (and will actually help accelerate getting those under-booty creases) is this: the cheap method I use is either stretchy headbands or garter belts. You slide them up your leg to where they sit directly under your butt. If the headband is a little loose, you can tie a knot in it or actually mark & cut the slack, then sew it back together. Put these on under jeans, or yoga pants or long skirts or shorts that are not booty shorts. They instantly make your butt look better/more defined line, while helping to develop that crease

They actually sell things to help "lift" your butt cheeks, and they sell bands that do exactly the same thing as cheap garter belts and headbands (I'm talking about the garter belts that grooms take off the bride and throw at the single guys at weddings.) You can buy these for really cheap online or in a novelty store or lingerie store or exotic dancer clothing store. If you try the headbands instead, make sure they're the kind that go all the way around your head/stretchy. They need to be pretty flat and not too wide.
