I saw Patience use this phrase in the Doc Martens thread and completely love it!

What items are the moms here using in their wardrobe that are completely killer (killer meaning not only totally stylish but also incredibly practical) on the playground, at the grocery store, in the carpool line, wherever?

I'll start ...
1. Skinnies with grey suede Merrell slouchy boots
2. Cowlneck sweaters with button-downs underneath
