Jacket's too small. If you want rolled cuffs, wear a short sleeve top under, so sleeves don't show. Aim for a jacket that hits about wrist length. The pants & shirt seem a bit snug, too. Tight clothes make people look heavier, not thinner.
@Sarah Anderson I like this idea! I will look for a pair of cognac color boots for the spring time that I can wear with my lighter dresses as well. You have great ideas, thanks for the comment!
that jacket is more fitting for a child. those boots need to be retired. the only good thing i can say about this is "you have a clean white t-shirt." start over!
