This is all I bought during the whole of October (that wasn't food, alcohol, desert boots or nail polish):
A shearling aviator jacket, £25 from Primark. I love this jacket. I umm-ed and erm-ed about it because it is Primark, but its really cosy and keeps me really warm.
Brow brush and eyelash comb, £4.50 from Boots. Always useful - I've needed one for ages. It's working pretty well so far.
I cannot recommend this Soap and Glory conditioner (£7.50 from Boots) enough. I use it with cheapy, own-brand shampoo, and it works like a dream, especially on my difficult to manage, out of control, curly hair. I discovered it by accident, when "Santa" left it for me in my Christmas stocking, and I haven't looked back - it really defines my curls and makes my hair super shiny. It smells nice too.
For the last four years (if not longer), I have used a Caudalie face wash (seen here). I felt it was time for a change, so I wandered into Space NK (one of my favourite shops in the world), and a very helpful sales woman helped me choose a new face wash, for £12. So far, it's working very well - my skin is clear, doesn't get to greasy, and, according to my mother, my skin has a 'glow' to it. I don't believe her.
Budgeting and buying everything for myself has taken some getting used to, but I think I'm doing alright so far.
