Since your're in NY (I'm assuming near the city), head to Cambridge Chemists at 65th and Lex. Then back down around 62nd-ish and Lex is Pasteur Pharmacy. Both carry a huge selection of excellent soaps - especially the high end English hard soaps - which I'm partial to.

I really like Floris soaps. If I had to choose one, Floris would proably be it - well, Tabac is up there too. Trumper soaps are very good as are DR Harris soaps. These all have scent. If you prefer no scent, try Mitchell's Wool Fat soap. Art of shaving soaps are also excellent.

Try a bunch and see what you like.
