Topshop's fall '09 look book has arrived and the collection is trickling into stores this week, with merchandise hitting the floor in monthly installments through November. The season is divided into four thematic categories: Horror Girl (sexy, punk-rock-esque rips and loads of leather), Manhattan Cocktail (short and sparkly cocktail dresses and jackets), Marianne (boho feathers and fringe), and Highland Fling (cozy knits and Scottish-inspired plaid). As usual, most looks are directly in line with the trends of the season, like the eighties disco dresses that were all over the fall runways. Here are some highlights from the new collection.
