Does wearing a floral bomber jacket in 2021 indicate poor taste in clothing ?

That is more like a long sleeve jacket blouse, sort of casual with a zipper. Probably fine for spring time.

It looks ok on her tbh, but she would make anything look good

No, wear what you like.

As always, it depends who's wearing it, and what they've paired it with.

No. Bomber jackets come and go depending on the trends, but they're pretty much a classic and a basic style jacket.  I like the floral jacket.

currently hawaii might be the only spot to wear that without judgement.

Yes. Bomber jackets were left in 2016 for a reason.

No. As long as it doesn't feature some dumbazz slogan like "I don't care" when the timing is insensitive toward social events.

Hm. I'm trying to think of an obvious example. Give me a minute...

Not necessarily. It depends how you pair it. Floral is making a comeback but the pic you posted does give me 2016 vibes. I’ll attach a pic of a more up to date posible outfit. The image and instead of the puffer the floral bomber.
