Vibrant colors have already proved a key trend at Milan Fashion Week.

With Gucci kicking off proceedings yesterday morning, the iconic Italian brand showcased its vibrant Spring/Summer 2011 collection based upon “grown up glamour.”

Prada followed this trend in its runway show, with a whole host of bright and jeweled colors being a key feature of the collection, which also included a playful, banana print and bold stripes. Elsewhere, Dolce and Gabbana proved the floral trend is set to make a re-emergence next summer, with a number of feminine floral pieces featured.

However, it’s not just bright colors that will be popular in the Spring/Summer 2011 collection - Alberta Ferretti and Luisa Beccaria both opted for romantic, ethereal-looking pieces, with pretty lace dresses and sheer chiffon tops. Additionally, the Fendi brand showcased a completely different style from the other collections previewed at Milan Fashion Week, opting for a more ‘70s feel.

The great and good of the fashion world are set to descend on the capital in the coming days to display their pieces, with shows from Roberto Cavalli, Giorgio Armani and Versace scheduled for later in the week. Anna Wintour is already in the Italian city and is likely to be in the front row and many events.
