Dip-powder nails once a month. I actually find the process of getting them done quite annoying and a bit of a chore, but I love the results and feel cheered up every time I look at my hands.
Skincare - I don't actually use many super expensive brands, but just looking after my skin morning and evening feels like a little treat somehow.
A posh facial spritz - always have a bottle in my bag and one on my desk and I always feel instantly happier and perked up when I use one.
Flowers. Not really anything fancy, but we buy a bunch every week from the supermarket or a cheap flower stall and they feel like they make such a difference to the house.
Eating out. We eat out a lot, often on the spur of the moment - doesn't have to be for a reason or a special occasion.
Perfume. I wear it every day whether I'm going anywhere or not.
Le Creuset mugs. I don't give a shit about any other crockery - we eat off cheap plain white plates from Ikea. But I love love love having my tea from a Le Creuset mug; they're the perfect size, weight and shape and the colours are gorgeous.
Cocktails, either while out or at home. I have a proper cocktail set to make them with, and various different glasses.
Sheepskin slippers with a proper sole. Game-changer. So much nicer than shuffling around the house in flimsy faux-fur ones, and somehow they magically seem to feel warming in winter and yet also cooling in summer.
