Jennifer Garner jeans silk Brentwood Country Mart

And even then, these are looking a little baggy ... just how much weight has she lost since giving birth to son Samuel 7 months ago?

Jennifer Garner went to Brentwood Country Mart to run errands on Friday, and Ben Affleck's wifey looked, dare we say, drop dead gorgeous? We're not sure what she's been doing to burn off the baby weight, but hopefully her hunky hubby is impressed with the results, because we definitely are!

Jen is currently busy promoting The Odd Life Of Timothy Green, and not only has she been killing it on the red carpet, but her street style seems to have improved quite a bit. Has Rachel Zoe been helping her out when it comes to her everyday wardrobe too?
