First impressions:
Royal Oud - the sandalwood reminds of Santal 33. No Oud. Pleasant but too powdery for me.
Nishane - Ani - interesting green top notes that are gone pretty quick, some rose\pepper and then just overwhelming vanilla\amber. Pass.
Diptyque - Tam Dao - almost non-existent on my skin. Faint woodness. Pass
Diptyque - 34 Boulevard Saint Germain - Nice spicy cinnamon/clove opening, floral soapy clean dry down. I think I like this the most out of the bunch.
MDCI - Chypre Palatin - Nicely blended as all MDCI usually are, kind of get an old school Chypre vibe. Lavender and Jasmine really come through on skin with some powdery-ness from the Iris backed with some spice. On the fence on this one... need more time.
Omnia - Ambra - No sure yet. Just took a quick sniff!
