I'm trying to find something definitive about if Melania was brought up in a religion, either culturally or in practice. I couldn't.
My point: Melania's scarf and dress were beautifully appropriate, respectful and traditional for an audience to the Pope. My devote Russian Orthodox grandma would've approved of Melania's choice. Ivanka, on the other hand, just can't help herself. Her hat looks like something one of the sillier members of the British Monarchy or a spectator at the Kentucky Derby would wear....it's all about her. The pearls and the slight low cut?....unnecessary and brings attention to herself.
JMHO.....as an appropriate and wonderful representative of our nation....First Lacy Melania is magnificent!
Re: religion, I thought Melania's family was Serbian Orthodox. But like you, I haven't seen any family religion stated in print anyplace, so who knows.
Read the news reports of their wedding. Melanias mother brought a large white candle for THEM to light that was used for her baptism.
(Her faith and religious practice is one thing she does not share with his other wives )
