The problem I have with most curvy jeans is they go up super high and make me look like I'm wearing frumpy mom jeans. And I'm 21. So no.
But there are non-frumpy jeans out there too!

I literally drive 2 hours once a year to the store in Gettysburg, as it is the closest I can find, just to buy jeans. They are that good and fit that well.
I wear a 14 with a big butt and thighs, narrow waist. There are three or four different cuts I can wear there, a variety of sizes. And to reiterate: THEY HAVE ENOUGH ROOM FOR YOUR THIGHS AND DON'T ASSUME THEY ARE THE SAME SIZE AS YOUR CALVES (zomg I hate that)
The house brand is what you want, and they tend to be $30-35 or so. I like the Taylor and Kaylee cuts best, but those sit about an inch below my navel. They have higher cuts.
Every year when I'm in there I see people going "Oh my gosh these actually FIT me!" It's crazy how many people look awesome in them.
