There is a giant front pouch for a bottle of beer...err...a bottle for your baby?
Swoveralls, a combination of two things you don't wear that you'll definitely want to wear.
"Combining two of the most utilitarian apparel concepts developed in the modern era, The Great Fantastic Sweatpant Overalls are functional, cool, and extremely comfortable."
From Thrillist:
"The Swoverall which feels like the Snuggie's
second cousin once removed, is currently available in two sizes and
comes in grey and navy. The company will have a version designed for
women hitting the store "very soon."
You could always go with the tracksuit look, but sweatpant overalls are a look that will make people ask, "What are you wearing?""
