I feel silly asking this but I'm doing it anyway... If I buy a pair of flip flops (the $2-$5 ones from Target or Old Navy) in a size 7/8, does that mean I wear a 7 or an 8? I am going to buy a pair of flip flops for my reception and there are almost no white ones in my size anywhere (even online). I found a pair that I like, kinda pricey but oh well, and they only come in whole sizes. MY dress shoes are a 7.5 and my sneakers are 8. I'm guessing I need an 8 but I need back up here!
