I need your help 
I was recently promoted into quite a senior position which I'm really happy about
.
I've always dressed according to the dress code which is basically smart casual. I've become so used to my flats and black trousers and dress mainly for comfort.
Now I have been promoted and I am part of a more senior team - I am expected to wear business dress and to be fair I want to dress to feel more assertive/confident.
Soooooo I need help with ideas for what to buy and where from! And where can u find comfy mid heel shoes?
I'm a size 12- 14, has
Does jewellery matter? What about handbags? And also what kind of coat/jacket?
Thanks in advance!
