The high-street fashion retailer has been in talks with Progenit, the consultancy set up by AKQA founder Matthew Treagus, and digital creative agency Poke.
The team are looking at ways to redevelop the existing transactional site at Topshop.co.uk, which also offers information on the latest collections and an online Topshop Style Advisor.
The consultation with Poke follows an 18-month relationship between the brand and agency, which has been involved in a number of projects.
These have included a tool that allows shoppers to personalise tattoos for Valentine's Day for printing out in store, and a facility to design and print out wrapping paper.
Last year, Topshop launched a mobile phone-style advice service targeting teenagers.
The mobile service extends Topshop's in-store style advice service and was developed by interactive marketing company Skywire. Customers can book appointments with advisers, receive advice and pictures of potential garments, and also reserve items.
In December, sister brand Topman invested in search marketing through Carat Digital, which ran across Google and Overture. Topman has committed more money online and aims to turn its site into one of the top five outlets in the UK.
