My daughter is having a beach wedding in April in NC. She wants me to walk her down the isle. Her colors are hot pink and orange. The groom and grooms men are wearing khaki pants and white button up shirts. She is wearing a long white "flowy" dress. The brides maids are wearing hot pink, the mother of the groom is wearing dark blue (I think) What should I wear?

What you feel good wearing. Sounds like somewhat informal?

It sounds like mix and match - I'd wear whatever color looks best on me. (If I wear yellow I look like I have jaundice, for example.)

Why don't you ask your daughter what color(s) she would like you to wear?
