I think that it is perfectly plausible to have a versatile wardrobe at under 50. I started out wanting no more than 12 bottles, but when I made a list of all the ones I wanted to do a FB purchase, the number was closer to 20. And even at 20, I feel like there are so many more gaps I want to fill, spectrum wise. I mean it's one thing to have a collection. If you're just collecting, go crazy! But if you want to use most of your fragrance, and in time, you would have to narrow down your choices to ones that won't be a waste of your time to wear.
Reading this: http://www.nstperfume.com/2008/08/19...llection-last/ and being someone who wants to actually USE my perfume, made me really want to have a modest (as in Basenote modest not real-life modest) collection of usable perfume.
