I know there is Nordstrom and Neiman Marcus. I also heard that there is a mens clothing store (Sam Cavato, I've never been there) in or near Frontenac Mall that has Amouage. If you've been to that one, what else do they sell?. Any other locations that are recommended for niche?
It's all going to be in West County. I live in Florida now, but there's a Sak's in Frontenac Plaza. You might also want to check and see what's in the Galleria.
My current favorites:
Bleu De Chanel, Dior Homme Sport 2012, Mauboussin M Generation, Zino Davidoff, Pal Zileri Viaggio D'Africa, and Rive Gauche.
