Oh I really shouldn't have added this up.
On myself...
Hair is £100 every 2 months, making £600 per year.
Makeup and skincare is when it runs out, but I use about 10 items and they run out say twice a year, so that's £200 a year.
I don't buy clothes/shoes every month. I buy workwear (suit pieces) in the sale, so probably pick up 2 or 3 items a year at about £100 each. Tops and casual wear, I'd say I buy 2 items a month, so that's say £100 per month. That makes £1500 per year.
Shoes I keep for years (other than summer sandals), so I probably replace 1 pair of shoes and 1 pair of boots a year, plus sandals. Say £200 in total.
Making my total spends per year on myself £2,500. Ouch. 
On the DDs...
School uniform - probably £150 a year, with one new skirt, a couple of packs of blouses, and a new jumper. The blazer lasts a few years. Plus tights. Oh and then PE kit probably adds another £50 with trainers and tracksuits and things.
School shoes - generally they grow slowly (thank the Lord!) so one pair lasts a year. I do buy more expensive shoes to try to make them last, so that'd be £50.
Dance/gymnastics/cheerleading clothes and shoes - they go through one pair of flat ballet shoes and at least 2 or 3 pairs of pointe shoes, so that's £100 a year. Then a couple of leotards/tights makes another £50. Cheer trainers are £70 a pop, and they usually get a couple of sports bras and shorts each, so thats another £50 or so. Uniform is eye watering but lasts years, thank goodness. I'd say total outlay on hobbies is £300ish each.
Casual clothes and shoes - extras tend to come out of their pocket money/birthday and christmas presents. Grandma is also a big spoiler! They each get a few new things for winter and a few new things for summer, probably adding up to £300 each time, making £600 a year. Then they get a pair of casual shoes/converse/pumps, plus a pair of sandals, plus a pair of boots. That probably totals £200 a year.
That makes a whopping £750 per year on each DD. And I have 4. And I think that was probably conservative, as I'm a bit of a soft touch if they see something they like AND I approve of. 
I just realised that my total clothing budget for me and the kids is £5,500 per year. No wonder DH is working overtime this weekend...
