Hi ladies!

So my cousin and his fiancé are getting married in March and I have a dress that’s super cute and would be a great option to wear at their wedding. However I’m aware that there are wedding etiquette rules or whatever that say you shouldn’t wear white to a wedding (an obvious rule of course). This dress isn’t all white though. I’m obviously gonna ask his fiancé if I can wear it because I like and respect her but what do y’all think???
