completely clean and tidy (about a room, a house, etc)
spic and span
in a position with the top at the bottom and the bottom at the top
upside down
with the usual outside parts on the inside
inside out
slightly ill
under the weather
as fit as a fiddle
to be very healthy and strong
something that seems to be bad or unlucky at first, but which you later realize is good or lucky
a blessing in disguise
