Really didn't enjoy this weeks crossword!!
25a. One in white vestment I excuse (5). I have put alibi but if right which I believe it is I cannot parse.

[scorpiojo]

Alb = vestment around i + I

[Lie-in King]

Alibi - 'i' (one, in) 'alb' (white vestment) + 'I'

You were a bit slow this morning! I had to wait 2 minutes and you didn't answer my previous question.
Going to look up alb and will try to remember word for the future.
Thank you!
