In my job with Topshop I am involved in the Visual Merchandising of the shop floor, making sure the the Topshop trends are represented within my own store. This can sometimes be more challenging than people think with concern needing to be shown to what lines of clothing are new in (these are given priority spacing as are best selling lines); giving visual balance (e.g. make sure your colours or prints are represented evenly throughout the space); outfit building (making sure a top is not randomly displayed by itself. It should be partnered with e.g. trousers or skirts and a jacket) and of course considering what is commercial for your store and customer.
I have some images of merchandising I have done in the past including mannequin styling. I will try to keep taking pictures of everything I do and post them as I do them.
