What the heck?

Anyone else see a problem here? I was picturing a seamless transition from my bathing suit to my butt, but instead I’ve got this double butt cheek effect. Is this normal? I thought maybe it was because they were too small but I went up a couple sizes and they sill dug into my cheeks like that but just got saggy in the middle like I had a load in my pants. Is it just the way I’m shaped? Is it the fit of this particular suit? Is this normal? Please help!

BTW: I live in a rural area where stores are limited and most stores hardly even have a bathing suit selection anymore because fall is coming. So if this doesn’t look too bad, let me know. I’m getting desperate for a suit and have a tropical vacation coming up! (Also I have never have luck buying clothes/suits/shoes online).
