If you only have work clothes - the black trouser and ribbed turtleneck you got four years ago at the Gap - you're not participating in your own style personality.
Style applies to a lifestyle. It's not about being told this is trendy, you must do it. Now people have more access than ever before.
I think that the way to have style is to accept where your body is right now, heavier or skinnier, whether you're going to change in the future and dress it as it is. The fact is you can always find clothes. It may be harder for plus sized people, I completely understand that. But I don't believe that it's impossible to dress with style.
Seeing, feeling, thinking, believing - these are the stages of how we change our style on the outside and our self-image on the inside.
Whether you're as healthy as you should be or not, that doesn't disallow you to look your best. Style is only possible from a place of self-acceptance.
Style is the instrument you can pick back up when you want to regain some of the confidence you've lost.
