I too thought shutters would block out too much light, but the look when fitted is so lovely, and with wider size slats, the more light they let in. The pics below have small slats but its the same style of bay with shutters. Also don't have the push rods on the front if you want a cleaner look. Having the slats split so top/bottom open separately like pic below is also good if you want privacy without shutting out light from the top. High gloss shutters also reflect light into the room and shutters seem to go with any look, period or contemporary.

Hi Susie, you said above that you are going for a Roman blind and wanted some advice on the fitting. Below are some points to consider. You can buy Roman blinds with various backings. As this is your bedroom, ensure that it definitely comes with a blackout rather than a dimout backing. If it is surface-mounted (i.e., outside of the window frame) then less light will appear down the two sides of the fabric. If it is recessed, you are likely to experience more ‘light ingress’. You can choose to have it manually-operated (e.g., via chains made of plastic or metal beads) or remote-controlled (via mains or rechargeable batteries). Although a powered blind is more expensive, it is rather fun to operate it from the comfort of your bed. You can even have it opening and closing automatically at sunrise and sunset (or at other periods) via a timer that knows your longitude and latitude, or from abroad (for security reasons) via a smart phone if you are into technological living! Joy.

There's another small one on the far end but this is the main radiator. Hmmm it's really interesting that your room is cosy as i've gone to trusty google and can't find anyone who says that radiators don't block the heat. It seems to be a big no no. I'm just so torn between function and fashion. I know it sounds silly. I think part of the problem is it is such a huge window that i would need more than one blind which would look a little odd. Then it isn't a usual height window in that it's quite close to the floor.
