It sounds like you are feeling intimated by this wedding couple. But you don't 'owe' them anything. They invited you because they want you to celebrate with them. The focus is on the bride, not you.
So ...
1) borrow dress
2) wear dark suit
2) buy gift or give cash $75 or what you can afford
3) go to wedding and have fun
