FWIW, historically, I have always found leaflet drops to be a total waste of time. I know that it really does depend on the market sector which you are in, but for your store, I would have thought that as Stefan recommends, the catwalk route would be a good starting point.
In the past I have worked with local fashion and photography students who do the legwork and actually put the show on and I have merely "lent" the products. If tied in with the local press and charitable causes it can raise the store profile quite well. Not sure exactly whereabouts in the NW you're based but I would have thought that you could quite easily accomodate four a year
Other things which have also worked for me in the past is liasing with complimentary retailers. Traditionally we have always marked our marketing calendar with key events, (not just Christmas but even things like National/Derby/Mothers Day,) and combined forces with other specialist retailers, whether it be florist/confectioner/card shop etc etc
Aside of that it comes down to paid for marketing which has never worked well for me unless aimed at the direct target market.
