Just about every "attractive garment" I have ever bought.
Oh, and hobby stuff. Hobbies I imagined myself doing and never made time for. Crochet! Watercolour painting! Embroidery!! I don't know who I thought I was, some kind of leisured Edwardian lady?!?!
Oh, and exercise equipment for e.g. aerial yoga. In my dreams, I glide around weightlessly, forming one pretzel shape after another. Not as easy as it looks in videos.
Oh, and perfumes. I went a bit mad during COVID and took a sudden interest in fragrances, maybe because they were the closest we could get during lockdown to a "change of scene" (in the mind's eye). About 10% of my blind buys turned out to be tolerable, luckily I'm a cheapskate so they weren't too expensive, but it does add up!
Oh, and fabrics. A few years ago, inspired by Strictly Come Dancing, I bought all these gorgeous fabrics and imagined myself spending the weekend fashioning a spectacular new wardrobe. My DH found me in despair on the Sunday afternoon trying to insert a lace panel for about the 9th time, and he pointed out that Vicki Gill probably had a bit more experience than me 🤦🏻♀️
