JLJACOBY,
Congratulations on graduating college ! How wonderful !! Don't worry too much about finding the right outfit. Find something that's comfortable because honestly, your cap and gown will cover your clothes for most of the day anyway. So, don't stress out too much. If you're looking to save money, try TJ Maxx or Marshalls. They're always having sales and check out Macy's too. I love their clearance racks ! They carry many different sizes. So, I'm sure you'll be able to find something.
