is this for your lingerie business?
you need to think about who you want to reach, and then how best to reach them.
for example, if you did leaflet distribution, how many male students would be the lone recipient of the leaflet? how many women over 50? how many men?
the royal mail "mailshots online" is the probably the best way to reach your customers, if it is for lingerie.

you can select who will get them, by age, gender, location. you can create or upload your mailshot, either as a letter or leaflet, and it's all delivered by the postman, which means people will be more receptive to it (i.e. picking it up and looking at it with their pile of post)
you don't have to buy the data either, which makes it much cheaper.
again, if it is for your lingerie business, then are there any other ways you can reach your target market? e.g. coffee mornings, perhaps home parties, planning a learn to salsa night with all of your products on display and available to buy...
