Jessica Simpson's weight loss is really starting to show.

After reportedly dropping more than 60 lbs. with Weight Watchers, Simpson stepped out on for an event for her Jessica Simpson Girls Collections at Macy's in Costa Mesa, California on Saturday -- and she looked great!

The blue, star-covered top may not have been the most snug piece of clothing, but it still clung close enough to her waist to see her progress in dropping her baby weight.

Jessica's sister Ashlee Simpson joined her for the event, with her short hair styled in a retro-looking updo.

This is the first we've seen the two girls out in public together since their parents announced their separation -- but it didn't seem to faze them at the event.
