As a lover of laundry scents, I think for me it's that many fragrances, particularly strong florals and orientals, can be overstimulating or intrusive. One of my faves so far literally reminds me of the inside of a dry cleaners! I like clean, light, low-projecting scents that don't come off too 'perfumey' and yet I can still smell through the day. I'm learning a lot about what notes and which houses I like, and which I don't - I think ambrox triggers the too strong thing, while ISO E doesn't, I like the house DNA of many Diptyque and Guerlain but not Tom Ford or JHAG.
SOTD: tried Bibbi Soap Club (thanks @IDontHateRainbows!) before my shower and WOW the leather is strong on this one. Really unusual, but I don't know who it would suit! Post shower: Byredo Bal D'Afrique, smells like an expensive hotel.
