Shoe Ideas

I have had such a problem trying to figure out what kind of shoes I want to wear on my special day.  I'm a very casual girl and I HATE wearing heels because they are soooo uncomfortable.  I thought about potentially wearing flats but it's going to be hot since we are getting married in August so they would have to be peep-toe.  Then I figure, why not just wear flip flops?  It's what I wear everyday anyway.  But I'm having a hard time finding ones I like that aren't super expensive.  My shoe budget is $50 but I would prefer to spend half of that if possible.  I guess I could buy a pair of white Old Navy flip flops for $2.50 and embellish them.  I've gotten pretty good at using a glue gun lately and my fabric and ribbon flowers are getting much nicer.
