I've just seen the price of Hermes nail polish (I had no idea it existed!) - £42 for a bottle!
I sort of agree with you re Etsy - unless you know the recipient likes the Etsy product/seller. Not on the high street - actually - there are loads of things I've got there for various friends and I know they've been eaten/appreciated.
I'm middle aged and I tend to find what I get:
jewellery - well yes, I do love earrings but I'm picky about what I get so please ask me.
Lush box of gifts for Xmas - again - I'm a bit picky about what I use/get. I also tend to get Rituals/L'Occitane - the Rituals I will generally use but someone got me a L'Occitane gift box in a scent I really didn't like and had to ask them if I could exchange it!
Having said that, friends have gifted me nice lavender or other gift sets via Amazon and although I wasn't sure on first glance, they were actually really nice and both have got used up!
I do have a posh lavender camomile tea bag set in the cupboard which I've never used!
I do think (I recently got a £100 Pandora gift card from supposedly close friends!) that you should be quite firm if you're fussy about what you like/don't like. Friends of mine know I love cats, clothes, earrings etc but sometimes unless you tell them what you'd like, they'd have no idea. E.g. a close friend, I know she likes Arsenal football club - big fan - so I ordered her a lovely poster - sort of Art Deco style - I sort of know her interior style but maybe I misjudged it, she liked it, but I was thinking out of the box.
There are various shops which I think I will tell people I love (Fenwicks, recently fell in love with them again when visiting Canterbury). But it was my birthday recently and DB and SIL got me gifts which DNephew (he's 4) chose - he actually has very good taste for a 4 year old! In fact, a couple of weeks later, I went to a gift shop near their house and bought two special gifts to cheer up SIL but he chose colour of one and something else.
One of my favourite ever gifts (but I chose him) was a kitten (as an adult) and I'd love for someone to give me a dachshund (yes I know I could buy one!).
In fact, I'd love to go to something like a show, have a cake made for me etc - a lot of the time, rather than other 'stuff'. Agreed with Prosecco, have way too much. I quite like scented candles but then there's the issue of if you have too many and don't burn them.
Following on from someone else posting - I sent DB a Betty's cake and he declared it the best ever. Also over lockdown, DB and family decamped for entirety to just outside Bath and I sent occasional care parcels of nice coffee for their cafetiere, Bath Buns, nice cheese etc - I knew it was a success because they loved it but also SIL texted me recently to ask the name because she wanted to send this to someone else in the area.
