Usually I make my own scents from essential oils. I like a mix of jasmine with a little rose and vanilla mixed in.
On men I like most scents, just so long as it isn't heavy. Mostly, I just like clean, fresh from the shower smell.
I wear Alchamy (sp) which I bought for 1.00 a bottle and now am addicted and it is kinda hard to find, but I love it and is the only perfume I can wear...I do wear Bath and Body works vanilla and jasmine on a daily basis because I am oddly not made of money and would like to smell nice!!
Hmm, I generally wear citrus/fruity scents, I'm not really a girly/flowery kind of gal, heh (exception is Givenchy Organza). Favourite perfume so far for me is Emporio Armani White for Her, and the range of mix'n'match scents by the Body Shop, particularly Citrella (lemon/lime/orange) and Aztique (fruity).
For guys I don't have a favourite brand or anything, I love spicy scents of all kinds *giggle*
