Can I convince my boyfriend to wear a suit to my sister's wedding?

Anonymous
My sister is getting married next month. My boyfriend is coming and it is the first time he will be meeting my parents. He is very uncomfortable with the whole situation. Because of his discomfort, he said it would be better if he did not have to wear a suit. My sister originally said that he didn't need to but then my mom said he had to since I am in the wedding party. Now it has become this huge ordeal. If he does wear one, he will be annoyed. If he doesn't wear one, my mom will be pissed off.

What can I tell him to try to convince him to wear one without pissing him off?

He does not own a suit. Also, my mom and sister told everyone at the bridal shower that he didn't want to wear a suit so now all the women know.

He's 25. This is lame. I just have to ask him and if he says no, I can't make him.. This will be awkward either way.
