I have always used both, deodorant and perfume, but not too much of either. Sometimes deodorant will still work well into the next day, especially if you don't do much moving around. But on nights when I do my yoga or clean my room, etc., I will need more the next day. Also, a "fast bath" as I like to call it (over the sink) will work wonders, if you're too lazy to go through with the whole shower/bath...like I am. *Note: I don't wear too much perfume in the summer, it attracts bees and they chase me. SCARED TO DEATH of bees, like you wouldn't believe. I run around like a fool when they chase me and I don't care who's watching. When I just stick close to home and don't have much contact with others, I'll be honest....I just skip the deodorant and perfume, because who really cares. I won't be around anyone anyway.
