Pottery Barn has some great options. Here are two that I liked.
This one would look fabulous over my make-up area. It has a girlie feel that I just love.
Crate & Barrel also has some great mirrors. They won't let me borrow their pictures so you'll have to check it out for yourself.
Restoration Hardware, one of my favorite stores I can't afford, has these beauties.
This is a leaning mirror. Maybe not good for houses with dogs or kids but still beautiful and much better than the cheapie full length mirror I've had since collage. (can't believe I admitted to still owning that thing)
This one feels antique to me. I love the small frame that doesn't detract from the mirror. And the side panels are so pretty.
Also try William-Sonoma Home. Hope this helps.
Another great place to look would be Ebay. I searched for "antique mirrors" and there were 880 mirrors for sale. I thought this one was pretty.
