I wear Coco Mademoiselle by Chanel, it smells different on everyone and you can wear it night or day.
Also Jean Paul Gaultier is classic and has 'layers' of fragrance and lasts all day.
If you want something a bit different, try Christian Lacroix's perfume, I can't remember what it's called but it comes in a gorgeous bottle and I have never smelled anyone wearing it!
Would probably be useful to know what kind of perfume you normally wear since everyone is different?
