For luxury brands, you may want to look at Europe, since a number of the companies are there. Obvious top choices for you would be INSEAD and LBS, as well as the Spanish schools (IE, ESADE, IESE). Oxford and Cambridge as well for safeties.
In the US, you want to be coastal -- either the NY schools (Columbia, NYU) or LA schools (UCLA, USC) since that is where the epicenter of the luxury/fashion industries are in the US. The other schools aren't really as good of a fit.
