Hot under the collar, like a buttoned-up garment? (6)

I believe the answer is:

shirty

I'm a little stuck... Click here to teach me more about this clue!

'hot under the collar' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?

'like a buttoned-up garment?' is the wordplay.
I cannot quite understand how this works, but
'like' could be 'y' (similar in meaning) and 'y' is found within the answer.
'garment?' could be 'shirt' (shirting is a kind of garmenting) and 'shirt' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for shirty that I've seen before include "Irritable" , "Ill-tempered (informal)" , "Ill-tempered or annoyed with a garment" , "Bad-tempered (like a garment?)" , "Tetchy" .)
