tucking undies that don't dent butt?

ok i couldn't think of a better title but there has to be other people with this problem. Tucking underwater gives my butt a dent (again, articulation is hard)? it surely is from how tight the elastic has to be in order to hold all the jewels in place but it bothers me. I got mine from tomboyX. I don't think going to a bigger size would work because it then it wouldn't be as tight to hold everything in place. I could always go back to ole reliable with the makeshift tube sock gaff but i find those don't hold as tight and things shift more frequently. so if anyone has figured out a solution i would greatly appreciate it <3
