There are so many types of people and cultures and people that are in different stages of life (college vs working single parent for example) that these questions become really vague.
But….no worries because we’ve all had these questions.
And my general advice is basic stuff:
Hygiene, form fitting clothes, and just knowing what you personally want.
There was a really old picture of basketball players in suits from the 90s compared to now.
People in suits long ago were always baggy and hung off of even the most physically fit people, no matter how great you are, a baggy loose suit is always unattractive lol. But now….a person wearing a suit that fits them makes them look like a billion dollars, just from getting rid of that excess baggage.
Its the same with clothes for anyone. I used to think hoodies were better large and baggy, because I thought it was “warmer”. But all it did was make me look like a criminal haha.
Now, a medium hoodie feels a bit tighter on me, but its just “snug” and makes me look great.
Little things like that go a long way.
