Hi Apartment Therapy,
I was wondering if anyone can tell me, where I could find a convex mirror like the one in Betsey Johnson's dining room? Preferably something reasonably priced (less than $200). Although we could find an exact match within your price range, we did find several eBay offerings well within your budget. Several auction items are available that are ripe for some DIY makeover. You might also want to check local flea markets or yard sales, because it looks like the retail options range anywhere between $370- $1600.
Of course, you could just purchase a safety circular convex mirror and have it framed at your local framers exactly as you want.
