For over 3 k you can buy a really nice LV bag!! The neonoé is gorgeous and half your budget. Or if you are going for a bag that is really popular right now you can go for the black Celine black drummed leather bag, it’s gorgeous.
I’d go for that LV bag if she like those kind of things. I just got mine and I love it! Otherwise you can also walk in the LV store and get her one of their scarves, they have all kinds of colors and designs, I personally think their monogrammed ones are quite nice, also not too high priced
You sound frugal when you dismiss a (comparatively cheap) Louie Vuitton bag as something she doesn’t need, and yet your Christmas shopping budget would bankrupt most of the people browsing this thread. It’s all a bit perplexing.
I can’t really suggest much more. You have listed her three interests but already stated that she gets that from you regularly, you also don’t seem to want to spend much time finding the gift so what comes natural to suggest to buy to a lady is a bag or a luxury itemn.
If you want people to give you advices that actually might be helpful you must give some insight of things she actually likes.
