The way I look at it, if your room is a mess now, he’s not going to hate you making the effort to clean it up. I can guarantee you that you can purchase some glam lamps and also clean up your bedside tables and he will be very happy.
Ultimately, things are returnable, so if you get something and he hates it, you can just bring it back! But he will probably welcome the change. Navy blue can be a beautiful accent color, so maybe start by getting some navy blue pillows and add those to the bed.
If you have the budget for a headboard, a light beige or cream headboard is glam, but not overly girly.
