I definitely noticed that there were many suits that were inspired by different uniforms (some were a little waiter-ish looking and some definitely very nautical-themed or inspired by captains). The nautical theme overall is very in this season anyway, not only in Moschino's collection.
The more dressy outfits and dresses had a very classical vintage look to them - a lot of pencil skirts and long gloves.
About the colours.. there was definitely a lot of black and blue but also white, red and beige/gold. Not much patterns and bright colours this time. The accessories were also quite classical and chic - captain hats, sunglasses, (long) gloves, longer necklaces, clutches.
Oh and one thing about the shoes - I noticed that a lot of them (if not all of them) had a peep toe. Peep toe shoes and boots seem to have become very popular this season. Next big thing? I think so.
And here are some of the outfits from Moschino Fall 2011 RTW collection..
This one is my personal favourite:
