Well.. this is when blogging starts sounding slightly dangerous.
I don't mind a change but of all the clothes you currently have in your wardrobe, there must be something that's not necessarily there for the sake of an I'm-not-boring statement, that's there because you feel like yourself in it, even if it's a silly blue sweater with weird prints on it!. A wardrobe isn't much different than a record collection, you may not play some songs for months or even years but they still mean something to you, even if they mean nothing to the rest of the world and are a part of yourself when you revisit them. And of course, acquiring the 'What's hot' compilation record probably won't help make it more exciting than narrowing down your own playlist.
Bad example maybe, but just sayin'!.
I would recommend
integration instead of starting from scratch. Take fashion with a pinch of salt and patience, and carefully buy guided by what speaks to you.. what creates harmony with the rest of your clothes but still pushes your own style on to some more creative level, it doesn't have to be loud, as long as you feel like a stronger version of yourself.. soon you'll find replacing some stuff and realising what really doesn't work and what does.
Throwing everything away is bound to generate some remorse, especially as you find yourself buying something new that would've made perfect chemistry with something you got rid of out of an thirst for what's new.
