Perfume can be really really expensive. And when you start getting into all of the body washes and shower gels and lotions and Such it can start to cost a pretty penny. So what I like to do is make my own scented body lotion.
Start with a unscented body lotion. Add one spray of perfume per one pump of lotion. Mix together in the palm of your hands and apply. I usually only do this on my arms and torso. I don't like to waste the perfume on my legs. Finish with a couple spritzes of perfume on top and not only will you smell great but this will help prolong the life of the scent. Layering is key!
I like to use Curel Daily Moisture and Aqua Di Parma Magnolia Nobile. Just make sure that you're buying unscented lotion!
