Today I had on a large amount of Gres Cabaret and several hours into drydown added old formula Organza Indecence. A spiced pie Moroccan market scent emerged. Love it!
For some more layering tips, here are some things I've found through trial and error and posted on other sites (BN doesn't seem as keen on layering as other placees, lotsa purists here). Lots of it is probably seemingly common sense:
The only way to really know with layering is to try it and not worry about it. So maybe don't use your most precious and expensive juices, but I certainly do anyway and it gives me a big giant thrill to be so decadent. I usually experiment with layers right before a shower or in downtime at home in case of disastrous results.
Some ways I guess at what might go together well:
1. The 2+ scents are in the same general scent family (oriental, floral, etc.), are soliflore to begin with (Lavender, Amber, or other single-name scents), or the scents represent complementing families (like leather with chypre or floral with oriental = floriental)
2. The 2+ scents share similar or compatible base notes--one with a stronger base and one more general. Especially if one is musky. I find musks layer best of any type of fragrance.
3. The 2+ scents combine to create a more complete perfume if one is mostly base notes and the other+ is a single lighter note perfume or oil, for instance: some Serge Lutens or CDG incense series are very "linear" and almost all base, so when combined with a traditional rose perfume or soliflore, a more complete traditional perfume emerges.
4. If you look up your favorite perfume's notes, find the most prominent then combine different perfumes that have those notes, the natural dominant character of the scent is thrown into new intensity (a bit like the "intense" versions marketed of many already).
5. Using lotion, powder, or cologne instead of perfume for one of the layers and then a perfume for the other seems to keep things less overwhelming.
I'm not saying anyone else will like these, and a lot of the combining has to do with:
1. Adding the second well after drydown
2. Using the cologne of one (weak concentration) and the pure parfum of the other (strong but close to skin).
When layering, I'm not that afraid of a bit of volume (being heard and noticed, not at all loud really). I also find that perfume isn't about being demure and careful when it comes to layering; it's a very deliberate and celebratory gesture to layer, all about the pleasure of the wearer and the slight uniqueness granted through combination.
Here are some combos I like
Guerlain Shalimar Eau De Cologne + Caron Tabac Blond
Comme des Garcons Comme des Garcons Series 3 Incense: Avignon + Pacifica Persian Rose
Dana Tabu (vintage cologne) + Jean Charles Brosseau Ombre Rose L'Original parfum = strange virgin/whore dichotomy
Serge Lutens Ambre Sultan + Jean Desprez Bal a Versailles (just a dab of the pure parfum as an accent) = blinding gold
Houbigant Quelques Fleurs (cologne vintage) + Houbigant Chantilly (vintage)= they just work together for me-- hyper-floral
Guerlain Shalimar Eau De Cologne + Caron Narcisse Noir
I really enjoy combining Guerlain cologne lighter concentrations with heavily concentrated pulse point only Caron classics. Highly irreverent, bordering on sacrilege? Exactly: and I love it!
Here are some I think would make great layering "background" perfumes for other scents:
Sarah Jessica Parker Lovely or any other musk
Molinard Les Fleur anything or most other near-soliflore scents.
nearly all of the Estee Lauders and Cliniques done as walkthrough only (there's something very archetypal about most of them).
Oldschool Cotys, Houbigants, and Danas in general.
gorgeous things with poor longevity (L'Artisan) + workhorse but linear things (Reminescence scents)
