Flat stats across the board. Bashful sounds balanced, but in practice every Pokemon benefits from boosting at least one stat. Use a Mint to change to Adamant, Jolly, Modest, or Timid. You're leaving a free 10% stat boost on the table by keeping Bashful.
Bashful is a neutral nature with no stat change. For special attackers, use Modest or Timid instead.
Modest
+Sp. Attack/-Attack
Maximizes special damage output
Timid
+Speed/-Attack
Outspeed threats while hitting specially

What does the Bashful nature do in Pokemon?
Bashful leaves all stats untouched. No 10% boost, no 10% cut. It's one of five natures that have zero competitive impact.
Is Bashful nature good?
Honestly? Never, for competitive play. Some people argue a neutral nature works when a Pokemon uses all stats equally, but that scenario basically doesn't exist. Pick a stat to boost.
How do I get a Bashful nature Pokemon?
Wild Pokemon have a random nature, so you might get Bashful naturally. Synchronize and Everstone breeding also work. But the real question is why you'd want to keep it.
When should you use a neutral nature?
Almost never. The only edge case is a Pokemon that uses physical moves, special moves, and needs every defensive stat and Speed. That Pokemon doesn't really exist in competitive. Even mixed attackers prefer Naive, Hasty, or another nature that at least boosts Speed.
