My sister is my MOH and sole bridesmaid, and, while she is amazingly smart, gorgeous, and funny to boot, she is not a heels girl. Lucky for her, I am not a bridezilla (hate that word), and couldn't give two hoots about the shoes on her feet. That being said, her dress is short, so I'll take it upon myself as bride and the more shoe-obsessed sister to find her a lovely, wedding-friendly pair of flat sandals to wear with her dress. Her dress is similar to the below, from David's Bridal and J. Crew:

And a few more sparkly options:

As for me, I'll be in these... ; )
