I need some help! This weekend I took my son to the park and I was wearing my hang around the house clothes, a pair of old yoga capri pants and one of my husband's old tee shirts. Not good!

I need stuff that can go to the grocery store, park, etc. I also need something a little dressier, but not fancy, for museum trips, birthday parties, that sort of thing.

Once I find a formula that works, I stick to it, so I need a basic outline and then I can go shopping! Help me!
