The trick is to keep it honest, keep it simple, keep it YOU!
I've seen many a good blogger turn into a PR media whore and when every other blog is writing about MBFW/Elle Awards/Fancy Shmancy Designer Collection/Bryan Boy then the point of blog and the reason your readers love it in the first place, goes to kak. You might as well join a PR team and ditch the blog.
Blogging is about YOU, about what you find interesting, inspirational, fashionable, your life, your thoughts, not a copy and paste of the press release you were sent and how yummy the cupcakes were at the event they lured you to.
It's a bloody shame it turns out like this and it's easy to get sucked into this pattern. So don't follow the crowd, leave that bullshit to them, honour your blog and yourself and get creative, be unique.
