No manmade fibres
I stick to my colour palette (HoC winter) - so don't wear any beige for example.
I only wear white, not offwhite (see rule above)
Silver not gold
I don't wear blue and black together (appreciate that's old fashioned)
only 2 or at a max 3 different colours at the same time
I don't wear just above the knee skirts as they don't suit me
I don't wear strappy tops to work - hangup from my formal days
Ditto strappy sandals
No see through tops to work
No jeans without high heels to work
Regular pedis, hair cuts, eyebrow sorting
Cashmere or cotton jumpers only (yes I know, I'm a ponce)
I tend to wear fitted things as they're more flattering
Bootcut jeans aren't my friend (or anyone's really)
Shorts/mini skirts wear them at the right length - cut off at the thinnest point of my thigh (this is a Trinny and Susannah rule that works for me!)
