(Apologies in advance, this got long!)
I've had a HoC style day and had had my colours done a while before that also by HoC.
Really enjoyed having my colours done, I totally "saw it" on the day and still only wear my colours. It's helped me branch out to wearing colours I'd never have before. I'd highly recommend it if you can afford it.
The style day though was imo not as much of a revelation for me and DFriend.
We were assessed on both our personalities (we looked at clothes we liked that we already owned and did some quizzes about our personality), and on our body shape (we were measured up and face shape analysed).
However we found that the conclusions drawn from your personality didn't always match those drawn from your body shape.
So for example under the HoC style "rules", it seems they have set characters for body shapes. Dramatic is angular, maybe tall, square jaw, etc. Romantic is curvy figure, voluptuous, flowing hair. And so on.
Our consultant really struggled with my DFriend having a personality and a body shape that essentially disagreed, and tried to push DFriend into a box that tbh just wasn't right based solely on her body shape.
I think she left a lot more confused than I did. I fortunately have a figure and personality that match so left fairly happy, but am not sure it was worth what it costs.
There was also a lot of dated info in there, current fashions aren't really taken into account, and (oh god I feel awful for saying this!
) my consultant isn't someone I'd take fashion advice from. I guess I would be well dressed if I followed their rules, but maybe not stylish/fashionable.
From a more positive angle some things said to me did click and confirmed what I was already thinking about myself and why I can't wear certain styles. I can look at some styles and tell you that they won't suit me.
I would suggest you keep exploring online and try to work out what you like and what suits you.
So try to analyse what clothes you are comfy in and why. Do you suit tailored clothes? Do you need a bit of frills/lace so you don't look boring? Are you the sort of person that looks "finished" in just jeans and a tee?
When you say "clothes you want to wear" do you think they would suit you or do you just like the way they look in the shops? I see loads of clothes I want to wear but I know they don't suit me.
Anyway. This got very long
and I hope it makes sense!!
