One of my favorite perfumerelated occupations is side-by-side testings on different themes,.For example perfumes that I think are quite similar, when testing them one on each arm, in most cases the differences are bigger than what I have percived from smelling the fragrances separately. Another interesting exercise is to test different strenghts (perfume, Edp, Edt) which also are more or less different formulas of the same fragrances. The most intriguing test is to compare formulations from different decades to find out how a fragrance has evolved from reformulations over the years. Such thrilling exercise are waiting this summer. Last week, on the monthly perfumelunch exhanging samples with Fragrantfanatic, I recieved some interesting vintagesamples from FF:s bargain on Tradera (swedish E-bay). Now I looking forward to compare the Madame Rochas EDC (70s) with the Madame Rochas Pdt (80s?) and current Madame Rochas Edt I have. Also the Grés Cabochard Edt is very interesting, the sample I received from the 70s to the Edt version I have from the late 90s. I know that the current forumla is pale compared to the late 90s formula, if the difference is that big also between the 90s and 70s formula, than the 70s must be impressive!
