This is probably going to be different for everybody, but it will be fun to see everyone's posts:
80's.....my coming of age years....'designer' perfumes like Georgio and Stetson and Lauren and Obsession were a big deal and really 'in', but I chose to wear more of a vintage perfume from the '40's which was having a bit of a resurgence at that time (as was vintage clothing)...White Shoulders....and I also loved to wear Hawaiian White Ginger by Avon- those were my go-scents back then. When I smell them to this day, they transport me right back to the 80's.....and so does Georgio, because my MIL used to douse herself in Georgio back in the '80's. lol
90's was the decade I discovered Poison by Dior and fell in love with it....and still White Shoulders, too (it smells like a mix of orange blossoms and honeysuckle to me my nose, both of which I just really love). I can totally see why you think of denim, though. The 70's also reminds me of denim, too....it was so prolific that at one point in the 70's I even covered my schoolbooks in denim one year instead of the usual brown paper bag covering. lol
2000's was the decade of vanilla for me.....Warm Vanilla Sugar, Black Raspberry Vanilla, Vaniglia del Madagascar, Vanilla Flower....vanilla, vanilla, vanilla! For whatever reason I just couldn't get enough of vanilla fragrances! Sometimes I would even dab on some of my vanilla extract. lol
