Weird butt

Since the beginning of 2017, I realises that my butt was uneven. I have one that is bigger than the other and I am really really complexed about it! I tried a lot of different workouts to correct it, but it doesn't work! And when I wear skinny jeans or shorts, you can see it☹️ If you guys have any ideas about what I should do or if you've had the same problem as me, please help me!
