Some great tips - love the camp cashmere suggestion.
When wearing long boots, make sure these are 1) real leather 2) well fitting -i,e no wrinkling or gaps at the top - these look so much better when these fit snugly at the top. Ankle boots are much better to buy and wear if you have skinny or large calves.
With some expensively dressed people I think they often look frumpy rather than stylish - I much prefer the Parisian look on me. I also love the way truely fashionable people dress in England - so much more interesting and fun but its not me.
Re colours, I look shit in camel and beige but fab in black (which unfortunately tends to overwhelm many people, and can look cheap on them - a mid navy or light grey would work better for them), dark navy and grey. I also wear a bit of strong colour e,g scarlet, cobalt, wine to add interest and contrast.
For those who want guidance about what style and colours would suit them, I would recommend House of Colour. Shopping is so much easier and quicker.
