duck off Lydia!!!! No one cares if you didn’t care about people wearing white to your wedding it is rude and not socially acceptable, just deal with it and wear something else. If you were actually a sensitive and empathetic person like you say you are you wouldn’t even be considering this.
No one is going to mistake who the bride is but for a guest to wear white and to even say 'oh they won't mistake me for the bride' just shows pure narcism.
It's really simple, white is reserved for the bride, if you are not the bride you can't wear white. If you are questioning if you can wear white then clearly you know it is wrong. Either ask the bride if you can wear the dress or choose something else to wear.
