Follow back

Can someone tell me how to upgrade follow back ratio? It is only 21% now... My account is about mens fashion, so i cant really find good account which followers i should follow... There isnt any account which followers are 80% men...And in what range should that account be? 200k-3m? 3m-10m? 10m+? Thanks in advance!

Offcourse you must follow back to gain more followers.
To gain followers ( men ) is it very hard to follow accounts " fashion " related.
Because 80%+ are women.
I would go for popular luxury accounts 1m+ follows

Find a very popular account in your niche.
With Many likes per post and 1m+ followers.
Because those accounts has a lot of new fresh followers each day.....

Thank you for reply.
