Kourtney Kardashian gave birth to baby Penelope not too long, in July and the proud mom appears to have already ditched that baby weight.
Kourt was spotted out in Miami, with the her boo/baby daddy Scott Disick and baby Penelope while she sported a denim dress that accentuated her tiny waist with a navy blue belt.
The reality TV star spiced up the look with nude Christian Louboutin heels and a classic neon orange Birkin bag.
With her hair pulled back, away from her face Kourtney shielded her bundle of joy from the Miami sun rays with a pink blanket over her stroller.
The oldest of the Kardashian clan has even inspired her little sis Kim to drop some weight. Kim Kardashian tweeted on Tuesday:
Both siblings look smoking hot to us.
