I found an interesting article on Babble on 10 fashions that give you away (as a mom).
Oversized satchel/purse? Check! Several in fact :)
Comfortable slip on shoes? Check!
Jeans out the wazoo? Check! I've got skinny jeans, trouser jeans, wide legged jeans, every day jeans...
Big puffy coat? I'm not sure how that says I'm a mom....it gets dang cold up here!
Flower summer shift? Don't think that has much to do with being a mom either; I flat out love sundresses!
Here's my mom fashion photo of the day :)
