Jessica Simpson is looking great ... and has the skinny jeans to prove it!

The new mom flaunted her fit figure on Saturday at Dillard's in Tampa, Florida, where she and sister Ashlee Simpson held another big press event for the Jessica Simpson Collection.

While Ashlee kept it simple in all almost all-black outfit, Jessica stepped out with some color -- sporting a pink blazer, patterned top and skinny jeans.

This is the second event like this the two have done together, both looking great as they promote Jessica's line.

The new mom has reportedly lost over 60 lbs. since giving birth to baby Maxwell back in May.
