First of all, I am a woman in my 50s (not a "lady").....
Secondly, and as mentioned, all women are different, so it's really hard to say. But, please, no cliches like scented candles. No mature female wants tat to clutter up the house - and nothing described as "posh", which is just the same tat, but slightly more expensive.
I would like:
Art gallery, theatre or museum annual membership.
Coffee or cheese monthly subscription.
Common or garden book tokens (do they still exist?), or Amazon vouchers to buy Kindle books.
Definitely NOT a spa day, or anything that involves the word "pamper" 🤮 Also, nothing "dainty".
Actually, I've just seen the budget.... sorry, I have expensive taste! So, maybe a good bottle of white wine (ie just one, value £20), but definitely NOT Prosecco.
Book or Amazon vouchers, as before.
Theatre tokens.
A smart notebook.
A pair (or two) of Seasalt socks.
Or maybe just take me out for a coffee and a bit of cake at a good, independent coffee shop.
