I am rubbish at fancy dress parties. This one is even worse, because it will be mostly people I work with - probably only 3 women in 30 people.
I am late 30's, OK size 10/12 figure (no bust) 5'6" and blonde(ish), so really I should be able to wear most things. Problem is that I have no imagination and that for work dos (even non-fancy dress) I usually spend so much time worrying about not being too sexy (tarty?) that I end up frumpy. Who can help me?
