I need a website banner for a personal fashion blog

Industry: Lifestyle/Travel
Design details: Hello

I'm an experienced blogger with fairly terrible design skills and I am currently setting up a new fashion blog called Girl With Curves. My personal style leans towards the 40s/50s, think Grace Kelly and Marilyn Monroe.

I'm looking for someone who can make me a banner ad to take the place of the current default image at www.girlwithcurves.co.uk. I'm thinking perhaps the London skyline in the background with Girl With Curves over the top. I like the idea of the silhouette of a woman with an hourglass figure (think big boobs and bum, small waist) wearing a fitted dress and heels walking towards the text, or perhaps she could simply be standing in place of the "L" of Girl or forming a curve as the "C". I'm open to ideas as I am so terrible with graphics. The colours should be black/grey/deep pink.

I hope this is of help.
Ideas for the visual style: See details.
Preferred colors: Black, grey, pink, white
