I absolutely adore rose gold
I have bracelets, a watch, earrings, and rings
all in rose gold, I like my outfit/gold colour to match so I would wear all rose gold items and not mix and match yellow with rose because my personal opinion is that I don't think it looks nice.
Most of mine is antique or vintage - the oldest being a hinged bangle, from 130 years ago and is one of my faves - but
do have some modern pieces, the more modern pieces have less copper than the older ones and that seems to be how it's done, shame for me because I like a larger quantity because it has a warm and richer tone.
I think the modern versus classic depends on the item it's made into, I think the design of it depends on how it's seen re: that kind of thing.
I do think that tanned and olive skin tones look the best wearing it, I have a mid olive skintone and love the way it looks, not so convinced it would look good on very pale/English rose tones ...... but until it's seen I can't really tell.
