Bad reaction to bloomers in comic play (3,5)
I believe the answer is:
hay fever
'comic play' is the definition.
(play by Noel Coward)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hay fever that I've seen before include "summer glums?" , "Coward created this" , "Pollinosis" , "Seasonal rhinitis" , "Allergy with asthmatic symptoms caused by pollen or dust" .)
