Body advice

I’ve been in a calorie deficit for a couple months now. I’m almost 19 and just really wanna get my dream body. My goal rn is to completely slim down but I would also like to work on my butt. I wanna make it bigger and more fit. I don’t have a big butt at all so it’s gonna be a lot of work. Would booty exercises affect me trying to loose weight (mainly in my stomach) should I wait till I’m at my ideal skinniness before I start working on my butt? Or can I just start working on that now too?
