There is a tiny blue bow on the front of my panties.
My BM just got married and his wife didn't have a something blue and we dumped our purses digging and in my 9 year old's purse was a tiny blue teddy bear lip gloss necklace and we stole it and pinned it to her garter. Now we have a really cute memory to go along with their big day.
My daughters "borrowed, old and blue" was my fathers ring in her bouquet. He passed away when she was seven. She was my fathers only grandchild and they adored each other. So, this was a way for him to be with her on her wedding day.
It was a surprise to her. She did not know until moments before the photos were to be taken, that is ring would be in her bouquet.
These are some really good ideas.. I am not doing a garter, so that kinda rules that out. I like the hair pin.. but I will have red flowers in my hair. Maybe I could get the inside of my dress monogrammed with the date in blue? or pin a ribbon with the date?
Since blue doesn't really go with my lime green color, I've been on the look out for subtle, blue things. I had blue sparkly stickers on the bottom of my heels that said "Mrs. AMJ." (I've attached a link, but you could pick these up at Michael's and do it on your own.) I've also seen really a really small, blue pearl that you attach to your bouquet. Even if it doesn't match your colors, it's really inconspicuous.
