Loewe. This way it would keep my collection quite minimalist since I can't afford them. I really like the casual bags they offer and the colors they choose.
If we're talking real though, since I don't like to drop more than a paycheck on bags it would have to be coach. Almost all of their bags are in that price range, they offer a variety of materials like smooth leather, pebbled leather, jacquard, Jean's and other fabric and coated canvas. They have cool limited collections. I also love how practical and well thought the bags are. I can't think of a more well thought bag than the rogue you get shoulder, crossbody, top handle which you can tuck in, easily accessible pockets and many sizes including the new 20. A lot of bags offer two straps as well like the regular swinger and the tabby line.
