The renewal of vows is a great gift for your MOH.
So far I got my bms straw beach bags, bathing suit cover-ups, pjs, passport covers, a book, sunblock, pashminas and body lotion set. I'm going to get barefoot sandals my wedding is on beach, jewelry for ceremony, a personalized surfboard towel, makeup bag filled with travel size toiletries and pay for the bm dresses. I think that's it, unless I find something else I can't resist buying :-)
