Day in and day out she has been hitting the gym or her Pilates studios in an effort to shed her baby weight.

So it wouldn't be surprising if Hilary Duff is tiring of wearing workout attire.

But the 25-year-old did her very best to jazz up her ensemble as she stepped out on Friday, wearing a snazzy varsity style bomber jacket.
