I wear CK in2U (her) and also a fragrance by the Gap called Dream More. Both are light. The CK perfume lasts a long time which is why it cost a bit. I used to wear another by Jean Paul Gaultier though I cannot recall the name but it was a nice bottle of a woman dressed sexy
Nice scent and it also lasts a long time.
The best thing to do when purchasing perfume is as others have mentioned, get a card and spray it, maybe rub some on your wrist, and then wait to see if you like it. Label the card too because often times I find cards for perfumes that do not match the name of the perfume. I agree, it really is too bad that stores do not give out those vials of perfume, I loved those.
