PotL is my favourite winter scent, and although it wasn't for me I could see Botrytis (Ginestet) being a great winter/cold weather frag.
The smell of Halloween for me is pumpkin and candle wax. Has anyone come across this in a frag? I've tried a few of the BPAL Halloween frags but they've all been way too sweet.
Christmas is pine needles and baking/turkey roasting. When I was little I used to lie under the Christmas tree and push my face into the Xmas tree branches, sniffing the warm pine needles where the lights were.
New Year's is ... hmmmm. Something opulent but effervescent. Recommendations?
