I feel the same way. I'm always like, wow everyone smells so good..do I smell good? My boyfriend laughs at me because sometimes I put so much (and probably too much) perfume on. I'll just take his word for it and believe I do smell good lol.
I usually put on perfume, and matching lotion anymore though. So, no need to reapply through the day I guess. Sometimes if I stop home for anything I will respray.
