There are more modest options for male Sims than female. I mostly struggle with finding modest clothes for female Sims, the men have longer shorts, tons of pants, long sleeves that aren't low cut and hardly any crop tops. There are absolutely some revealing clothes for the men but not like there are for the female Sims. I'm all for more modest options for male Sims too.
I'm a woman and tend to play female Sims more than male, I wouldn't wear most of the female CAS outfits because of how revealing they are. It's fine to have the option but it would be nice to have a few more pieces that aren't revealing. Some people just aren't comfortable showing a lot of skin.
