What outfit(s) does Ciel Phantomhive wear most often in the manga/anime?

[tori]

I really want to cosplay him, but I need to know which outfit to buy. I can't find anything particularly good online, and I am looking to buy to to my inability to sew. I also have some questions on the color contacts. If you can please provide links on sites to buy good quality cosplay, along with the actual outfit; it would be appreicated. ^__^
