It's a small, pretty, fancy, evening bàg.
I don't understand the love or the hate. Some of the love is completely OTT (it'll be a great conversation starter") and some of the hate is completely OTT ("it's so dated and old fashioned")
There are 100s, probably, 1000s of small, fancy evening bàgs on sale from Matches/ Anya Hindmarch / Erdem at one end to well, whatever down-market China website floats your boat.
It's a pretty bag and fancy party dresses will generally look better with a small fancy bag.
