Introducing DisneyRollerGirl, editor of DisneyRollerGirl, freelance fashion editor and all-round fashion insider. As the second editor in our London Fashion Week Guest Editor series, DisneyRollerGirl talks us through her favourite AW12 Reiss pieces and will be reporting live from fashion week all day today.

Anastasia shirt. I like the contrast of masculine cut, feminine fabric and deep inky blue colour of this lace shirt.

Steph cuff. This simple, sculptural cuff is the kind of quite statement piece I really love.

Callister cardigan. I’m a huge cardigan fan and this slouchy boyfriend style comes in a lovely trio of rich YSL shades.

Rosalie blazer. This is the sort of grab-and-go blazer that can be formal or casual. I prefer casual so I’d wear it unbuttoned over a well-worn pocket tee with my favourite gold chain necklace.

Palermo shoes. The highest heels I can manage are 100cm (at a push) so these tapered cone heels are perfect. I like the unusual colour and classic almond-shaped toe.

DisneyRollerGirl is taking over Reiss social today and will be tweeting @Reiss, and stay tuned to the blog to read her round-up of today at London Fashion Week.
