How to do cardio without losing weight?

As a naturally very ruler shaped and slim girl, my focus in the gym is trying to create curves with heacy weight training. I do not have boobs. I will never have boobs. Whatever. Skinny thighs or thicker thighs, I just don't store any fat on my arms or chest. Though, my bones are thick here, so it's not like I'm blessed with a sexy pear shape to compensate for my lack of boobage lol.
Anyway, I really want to start doing some cardio. I spend a good hour in the gym six days a week but it's all weight training and some light pilates moves. I do about 3 or five minutes on the treadmill to warm up, though.
I always feel great when I do cardio. But I'm too scared of loosing weight to do any! I love how cardio makes me feel fresh and clean on the inside, and I find it amazing for my skin. But I'm trying to get some curves here, so I'm trying to build muscle and gain some healthy fat to get a rounder booty.
