Requests like these are why I have been in so few weddings! My eldest sister asked me to dye my hair either brown or blonde for her wedding so I did not clash with the bright pink dresses. A "friend" of mine also asked me to dye my hair. I was also asked to lose weight ("just" 10-15 lbs) despite that "friend" knowing I had eating and body issues because of my odd shape. (It was before I was diagnosed with lipedema.) My husband was bullied into cutting his hair for one of his brothers' weddings. It made his depression worse. His second brother and his fiancee wanted him to shave his sideburns and cut his hair. Their wedding was roughly a month before our own wedding. To be fair, they did not know about our wedding, but even after they found out, they still made comments about how his ponytail made their pictures look trashy. The fiancee-now-wife in question even said that a haircut would have made us look less like 'lowlife garbage people" in our own wedding pictures. (I dislike her a great deal.)His third brother did not request anything like that.Double volcano for people who hit babies.
I'm super cranky about the wedding industrial complex in general, let's call that my pet peeve, lol. But, yeah, I see advice columns about how someone's bridezilla/groomzilla "friend" wants them to cover up a tattoo or dye their hair or lose weight or whatever, and I just wonder WHY they'd even ask them to be in their wedding. I don't get it, especially after they already asked them to be an attendant.
