You absolutely need more sweet pea tops. That top is amazing on you.
The dress: love - what a great color on you! And burgandy boots will be quite scrumptious with this. A purple purse would be great too... purple is going to be popular this fall. I would also love to see the leather jacket over this dress - for a more casual look.
The trench: I think it fits you well, but try sizing up. My only worry is that the trench is shorter than the dress. I think Angie likes the hemlines to be the exact same. I recall she is a stickler about this. So, the question is, "Is the trench too short, or the dress too long?"
I can't tell from the photo, but I'm wondering if it's the dress that needs to be shortened? Can you hike it up at the waist, so the hem falls at the knee, and take another photo for us?
