I generally dislike fragrances that make me think of something to eat.
... the only non-gourmand commercial coconut I know is Versace-Crystal Noir. The coconut is obvious-stronger coconut note id edp- (you know,based on the classic succes combo, tuberose+coconut ideea), yet it's not foody, and it's easy to wear, even with ellegant clothes maybe.
P.S.-for more tuberose,and coconut is smaller dose, try Beyond Love by Killian. Divine tuberose+coconut.
P.S.2- I now see it's for your girlfriend--- if you can get her a "Beyond Love", you'll totally impress her, as the presentation (gorgeous, luxurious box) and the scent (best niche tuberose-coconut) are incredible!!! There's no way she's not gonna like it. The price is very high though...
