Yes they can set any rules they want but we can also criticize their rules. Works both way la pundek. The issue is not colorful dress in a black tuxedo event, the issue is how come Malay traditional dress is allowed but other traditional dress is not. No wonder UTM considered sohai university when got alumni like you.

You do realize that they set the dress code right? They DECIDE that baju kurung is part of the dress code ya? It's not as if they go:
"OK time to decide Dress code. 3 cm from ankle, 2 cm max from wrist. Hmm let's check which type of clothings fit into this dress code?" "Ok baju kurung fit, oh too bad baju kebaya don't fit".

They MADE baju kurung to be part of the dress code, there's no fit or whatever la.
Topkek betul, if this is UTM grad level I donno what to say.
