HELP

Okay just to get straight to it, I`m going with my boyfriend to his prom and he wants to wear LIME GREEN!!!! YUCK I mean I can`t tell him NOT to wear it for the fact it is HIS prom. I found this gorgous gold dress but yet lime green and gold....lets see....doesn`t mesh well. I found this really nice suite that is white with gold tie and gold vest, and he thinks it is "boring." I went to the mall with his mom yesterday and she loved the gold dress to but she is the glittery, sequen dresses that I`m in to form fitting dresses but yet she said I could dress up my dress some with sewing some stuff that I can`t remember but I don`t know what to do the fact my boy friend said he doesn`t want to wear gold but i think it would look really nice. I`ve tried looking for Lime green but then I thought about it if he wears a full on lime green suit I can`t wear a lime green dress because 9 out of 10 the greens are going to be different. I think this gold thing will work but then last night he was talking about Baby Blue, now that is something I think I could SORTA work with but I don`t know. His mom wants us to wear black and white but that is so boring and what a lot of others will wear. Now i now I sound like I don`t want to stand out by not wearing green but I do just not with that color, so I don`t know what to do really. PLEASE help me out!
