Go for the Eva, it is very nice and versatile.
If it weren't for the price I would've bought one. I can still remember when it was first release it was less than 500 USD ... I really regret not buying it then
De eva is a good choice, It will be my next purchase! I want to get it before it cost anymore $ Then i won't be able to justify the price for a small bag.
Also another would be alma bb de. Can fit a bit more than the eva
The Bloomsbury will hold quite a bit more than the Eva, but it's a totally different look. I think Eva can be used for more dressy events. Bloomsbury is more casual, IMO. The Favorite might be a good one to consider too. I think it can go dressy or casual, more like the Eva. Good luck deciding.
