So I've been working on my style, and here is a sample of what I've discovered looks good on me:
This outfit is very similar to what I'm wearing today. The cardigan I have actually has embroidered flowers on the front in green, blue, and tan, and, while I haven't worn it yet today, I will take it along tonight to Worship Team Practice, in case the air conditioning is a little too persuasive.
I've found that for me, wearing basically all one color makes me look really sharp. It's not really "cool," since this season we're all about that "pop of color," but there it is.
Since I've discovered Polyvore, I think I'll do more of this. Won't that be fun!
