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.
Self-esteem doesn't come simply from dressing well, but they are both something we can control. It's a missed opportunity when women say they don't have the money, figure, etc., because style is such a way to help cultivate the way women feel about themselves.
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.
Never let a trend get in the way of creating a great outfit for yourself.
