researching and designing...where on earth do I start????

It's week one and we've started researching for our final year collection in our Fashion design and Technology course... I am completely overwhelmed and have no idea where to start... I know what I like though, so I guess that's a start... I love the 1950's Dior "new look" silhouette with the long elegant gloves... I also know that I definitely want to do a cocktail wedding theme, starting with cocktail dresses and then my finale piece will be an extravagant wedding dress... after all, who doesn't love a good wedding dress? :-) I do love the classic looks... but I DO NOT want this to be boring at all... So I have to discover what I want to do to make my collection different and interesting... I LOVE COLOUR... I'm considering a relationship with one or two vibrant colours paired with an ivory of sorts... Here are some images that have inspired me so far...
