You could have a lot of fun with this by experimenting with many different looks over a period of time - and decide which brings out the "best" part of you. What are you wearing when you feel at your sexiest, most confident, most vibrant...
Another way is to grab some magazines - not too old because you don't want to be too out of date, unless you're going vintage... page through them and tear out any images of anything that grabs your attention and imagination. Most of this will be pictures of clothing, but you might also find yourself attracted to pictures of interiors, travel and nature pictures, pictures of make-up (like nail varnish colours) and hair colours or styles. Lay all these pages out and see if you can find a pattern that seems to indicate where your tastes are heading now. You might find something really obvious like the new hairstyle you want, and you can take it to the hairdresser to copy - or you might only see the colour scheme that is "talking" to you right now.
Any small clue is worth listening to. Have some fun with yourself! <img src="/images/graemlins/smile.gif" alt="" />
