Plus Size Jacket

I'm a Plus Size. I need a lightweight, summer jacket for work (as an administrator in a hospital.) I'd like it go with most of the things in my wardrobe. Too much to ask for? Thanks in advance.

Not a problem. Look for something with a defined waist, in a neutral color and a summer weight fabric. Be sure that the hem hits right at the sweet spot on your hip; not too low. When you wear the outfit, try for a contrasting color for the shirt underneath. If you really want a slimming look, wear three colors; as I explain in my post here: "Prominent"
And, BTW, here's a Jacket.
