Right now I am enjoying 3 really good lavender scents, all with very different concetrations and pyramids, but all of them really comfortable for me:
Creed's Royal Scottish Lavender
Caron's Pour Un Homme
Yardley's English Lavender
and the relatively new 4711's Lavender & Thyme.
Only the last one is not considered a classic since it came out just about 2 years ago, and it's very good to me, intensely fresh for the duration of the scent, all of its 10 minutes. (maybe a bit more). The combination of the 2 main notes is great.
Creed's scent is rich and forceful in all its lavender top-mid notes then it changes into a classic woodsy sandalwood and spices bottom. The descent is rather fast though.
Caron's is more of the caveman lavender that wants to be romantic, i don't find it particularly elegant, but many elegant men used it and it is now considered elegant for that sole reason. The base is a darker and sweeter vanilla and musk. This is the one that will last the longest of this small selection.
Yardley's is a simple and "what you see is what you get" Lavender and it's great for the skin, for linens, for the room etc. A very honest lavender. Contrary to popular opinion, this scent doens't have just lavender but many other ingredients (it has other florals and musk) and they contribute to the fresh and stable quality of it.
