Stupid Invite Question....

I'm trying to decide between a pocketfold invite which is 5 1/2 x 5 1/2 , or a 5x7 flatcard.
If I choose the pocketfold how do I frame it? I'm asking because I registry stalk (lol) and see that someone bought my 5x7 Vera Wang invite frame which I love!! And I want to use it! Can the pocketfold go in that frame f folded over? Will it look dumb? Or do I get a special frame? I really have no idea..LOL
