In terms of the aesthetic look of the VK style, it really seems to be tailored to look best on thin people. True of 99% of the world's fashion really.
If you can pick out things that work for you and you feel confident wearing it then you should be able to pull it off.
And personally I think there is nothing wrong with losing weight just to be able to fit into and feel good in the clothing you admire. I'm doing that myself right now. Hell, it's good for you and it's much easier to start new health habits, lose weight and rock an awesome look while you are young! And it's not like you have to aim too small. Just aim for one size down and see how you feel!
I've managed to go from an 18 to almost a 12 in the last two years and it really is great. Good luck!
