I’ll answer as Maezawa.
Since there are many men in their 40s and 50s, if you’re receiving offers from men in their 40s and up, they don’t seem particularly young to me. Or are you saying that you’re having trouble because you’re getting a lot of offers from men in their 30s?
Many men in their 40s and 50s seem to prefer women around 30 because they feel they’re more mature and composed. (Though some do prefer younger women.)
That’s why, generally speaking, many men want to make offers to women around 25–35.
If by women in their 20s you mean women around 20–22, it’s possible they’re being rejected simply because of their age, rather than because of what they’re wearing.
Even if you ignore it, your age increases by one every year.
For now, if you accept offers from younger men and gain more life experience, I think that once you’re over 25, you’ll naturally start receiving offers from men in the age range you prefer.
The key is that life experience. Once it begins to show in your appearance, I think you’ll receive more offers.
Women who look seemingly refined and proper, as if they wouldn’t respond even if approached, yet somehow give off a subtle sense of eroticism, seem to be popular.
That said, everyone has different tastes.
For now, I think it would be best to focus on improving yourself.
As for clothing, of course everyone has their own preferences, and I’m not really sure myself, so let’s wait for someone else to answer.
