Jacket is Key Job-Interview Attire for Women

Tammy writes:
I am a slightly plus-sized woman and wonder if it would be inappropriate not to wear a suit to an interview? Would a professional wool skirt and nice wool sweater be too casual? I am larger on top than at the bottom and suits are difficult to find plus costly. What is your opinion?

The Career Doctor responds:
In my opinion a jacket is the key piece. You don’t need to wear a suit but you should wear a jacket — over a dress or over a blouse (with skirt). I do think a sweater would be too casual.
