"I mean the comments that people make hurt me becasue I don't want my mom to feel bad."
She's lucky to have a son who cares so much about her. On that count, I suspect none of the things people say about her are anything she hasn't dealt with before, she's probably able to handle it.
There's not much you can do about rude people, no matter what they talk about, but learn to deal with them.
"But another problem that I was afraid to bring up that others have hinted does deal with my mom's new look. I mean it is kinda hard to look at my mom's new figure. [...] I mean it is hard to see your mom dress in a way that men make comments about and look at."
The alternative might be worse - sometimes those who reach middle age (it seems to be men, mostly) embarass themselves by trying to act like teenagers again, and failing completely. Imagine a middle-aged man who gets a mismatched toupée and starts going to dance clubs and chatting with teenage girls...
Divorce can be tough, especially on those who feel that among other things, it means that they're no longer attractive to anyone. Men sometimes join a gym and start working out to feel better. Women may go from a shopping spree to cosmetic surgery, including breast implants, face lifts, and so on.
Being able to feel attractive again sometimes helps them put some of the feelings of divorce behind them - the fear that it was because of their personal flaws that it happened. Even when you know better, it's hard to reasonably discuss things with your emotions and win the argument.
I expect you'll be able to get used to it, but it'll be a bit uncomfortable until you do. On the other hand, if you do mention it to her, maybe she'll be willing to tone it down in front of you (reading some of the posts here, those who are mothers are often concerned about what their children think).
Anyway, good luck.
