HOW DO I MAKE PERFUME LAST LONGER?? UGHHH

I am 21/F and I am someone who sweats MASSIVELY. You could say that I tend to get a tad bit stinky when I start sweating. Like when I enter s room with the ac on, i can smell my sweat :( I've tried multiple things. I've used perfumes, lotions, perfumes on top of lotion, lotion right after bath, bodywise underarm roll on, and perfume with vaseline as base so it last longer. Nothing works. The same good "long lasting" perfume last veryy longer in my sister but when I use it, the minute I step out of the house, gone. Not trace. At all. Do I bathe myself with lotion? What should I do? I really wanna be that kinda girl who makes you think "oh she smeels great" when they walk past :(
