Three blazers, five looks this month, ordered most formal to least

Three sack-cut blazers across five looks this month, ordered from most formal to least: a grey blazer worn as a suit, a navy double-breasted, and a navy gold-button.

What I want feedback on is where the balance tips. Once the trousers stop being tailored, does the jacket still look deliberate, or does it start looking like two outfits fighting each other?

Honest takes welcome, especially on the last two.
