I like the first ones because they don't have holes in them
I like 2nd
I like the Michaela (the first one) better, because I prefer the silhouette it creates, and it's (in my opinion) more beautiful because of it's simplicity :)
Although PERSONALLY I prefer the look of the first pair, I think that the second pair would be a better buy. They are cheaper, and more versatile. You could wear them to casual, semi casual, and maybe even formal events, and they are VERY Summer-y. Also, they'd be good for early fall. Just my opinion though, they're your feet, girl!!! Happy shopping! <3
