My sister is planning her wedding and plans to make her husband wear a mangalsutra too, thoughts?

My sister(cousin)'s getting married next year to an Italian man and her husband had been intrigued by Indian culture and asked if we have an equivalent of wedding bands, my sister replied we have mangalsutra and sindoor only for women.

From there, she got the idea of making a mangalsutra for him too, just a plain thin black and gold chain to match her mangalsutra. They are gonna have two weddings, one christian and one hindu.

Her husband doesn't seem to mind but she's nervous about relatives and social media reactions if she posts photos. Ik that mangalsutra bracelets are trending for men rn but they quite literally have lost its meaning because mangalsutra is a chain

She wanted to have something from both cultures that they both can wear in their married life to be connected to their roots. Thoughts??
