I want a very specific type of shoe for my wedding which will be very hard to find (red sparly...I am from Kansas after all). I found some that will work but are 3 inch heels, and I don't think I can stay in them to dance all night, so I'd like to switch to flip flops. If I hem for the heels, how big of an issue will the hem be when I switch to flip flops? (Enough that I should keep looking harder for more comfy shoes to wear all night?)
