I can understand feeling self-conscious. Someone made a great point that the focus will be on the guest of honor. As much as it may bother you, remind yourself that it's not all about YOU. Not to sound harsh, since I don't know you, lol, I just know that for me, I would always think way too much about what others were thinking, when meanwhile, I wasn't the most important person in the room, nor were they all spending that much time thinking about me. Get yourself a new outfit and go have a great time!
