Step 1- Look at Cure magazine. Most probably know this as one of the most popular VK mags out there, and lucky for us that speak English and not Japanese, they translate one or two interviews into English in every issue. Apparently there's also Cure USA? (I haven't been able to find it...) There's also a Cure app for the iPhone/ iPod touch in US iTunes which is free, though you do have to pay for each digital issue (comes with one free, and it's VERSAILLES!). In each print issue, there is always a section dedicated to new clothes by the major brands to create your own looks, and a Hangry and Angry cartoon is always featured. Plus, styling tips for hair and makeup. Follow the pictures you don't need to read Japanese to figure it out! But even with just a little online searching of your favorite bands, you can easily pick up elements to add to your own look.
Here's a spread from the latest Cure with...D=OUT! Was so surprised and happy when I found this. Though I think Kouki's style on the left is a bit more wearable, I love that look on the right! This looks a little more formal and has a sort of understated elegance with just the blazer and a couple of well placed chains to add a bit of punch to the styling.
And for oshare-kei bands, go decora! Look at SuG from Pink Masquerade PV. Prints, anyone? And look at Shinpei's headphones!!!:
Any style you choose to emulate- have FUN with it! This is probably one of the best things about VK, because dressing the part is so important to the bands. It's also some of the most fun for the fans!! So go out and enjoy!
