Gawd, I love those red Sidis. I've got them in white though, so I'm not allowed to buy a new pair of shoes.

It's easy enough to start building a whole wardrobe of biking gear for mood, weather, distance, ride intent, etc. but I've definitely been building mine based on taste. I have a shebeest jersey (black with fleur de lis design) and I've got a pair of shorts from BornFit. I lie the jersey, the shorts are better for short rides. I also have some pearl Izumi shorts that are working well for me now, but I plan on getting some of those LG neo shorts, and some longer Capri length leggings, as I hate hate hate sun exposure (I'm very fair and tend to have allergic reactions to too much sun). I have a TwinSix jersey which fits really nicely, and it doesn't have elastic around the waist or sleeves, so it breathes and moves nicely. T6 also has some cute kits (I'm dying for the Vixen kit, which would go beautifully with those red Sidis. You should buy all of it, lol).
