My collection is split between Amsterdam and Stockholm, so I can't check any particulars. I do know that Guerlain dominates. I have 13 different Guerlain fragrances, many of them in different concentrations and with backups of many of them (sometimes multiple).
Chanel is less well represented with 9 different fragrances. Some in different concentrations and with backups (multiples of some, especially of No 19).
