Hi,

Well I would have to say no. I remember at one wedding sil was wearing a white dress, actually i think she's worn it to a few and I thought at the time oh she's wearing a white dress and it didn't seem wrong...I think the style of the dress helped I think it was a cue dress so not bride like. However, I would say that lots of brides might not like it and you won't know if this is one of the brides that would mind and even though it might be silly to some it is their day and I suppose as their guest I wouldn't want to do anything to upset them just my opinion though
