A premade picture frame probably would not work because of the dimensions. The closest frame sizes would be 6x8 or 5x7 (I dunno the dimensions of the lilli). But either way the ratios are geared more for 4:3 not 16:9 and wouldn't be a good fit. Your best bet(barring building it yourself) is getting a custom made frame from your local framing shop. I dunno what kinda money they would charge but it shouldn't be too bad because of the size and its not matted.
