Chloe, the YSL chain bags, MCM, etc. can feel a bit naff sometimes due to their ubiquity but it's a step up from the dreaded MK, DKNY, Tory Burch, and the rather predictable Mulberry.
Salvatore Ferragamo is a bit like BV but can feel a bit mature, I think the newer models from Celine and the less recognisable models (so not the Antigona) from Givenchy make for good understated elegance but probably pushing the limits of your budget, though, in the sales you might get lucky.
Love Marni bags, and currently liking the look of Victoria Beckham, J.W. Anderson, 3.1 Philip Lim, Loewe, Tom Ford, Carven, and Proenza Schouler but they tend to be more contemporary/minimalist so may not match up to your tastes.
There was a mention on here a while ago, can't remember it now but it was a Spanish high-end brand similar to BV but differentiating enough and more affordable.
