The same pics are used for "Brands at Topshop", it's not like she's actually advertising the maternity collection, haha. Imogen and Alana are only featured with a single pic on the website, but it's totally irrelevant, the girls usually have the same amount of ads (roughly)...[ I can't believe they only use this model once and it's for the maternity wear section!!!]
