Despite Cinna's death, his designs remained crucial to the rebellion. Likely knowing his death was unavoidable with the incoming war, Cinna had already designed her mockingjay uniform, secretly designing it in the few weeks before the start of the 75th Hunger Games and gave it to Plutarch Heavensbee. The Mockingjay uniform was concealed as Katniss's wedding dress requested by President snow, which transformed after becoming ignited when Katniss began twirling on stage.
this means that Cinna's designs were rebelling over the games as he did a mockingjay uniform but it does show how he doesnt agree with the games real meaning (also i dont know if this helps but i manly think cinna was the one who really rebelled in the style team as the other members only talked about how brutal is was even tho they sounded very arrogent) hope this helps!
