(Especially like the gap between underwear and skin between hip bones and abdomen.)
This building is not on the tour, but I think it should be (I like art deco):
On a previous day, I noticed an interesting slum when driving past on a mocy, and remember pictures from the internet. Interesting because it looks like it was built as normal housing, and then became a slum (whereas all slum I saw elsewhere started as slum and are only one or two floors). Southeast of crossing of Sihanouk Blvd and Sothearos Blvd.
Then dinner, walk back, go to bed early (midnight) for an early start (8 am) the following day.
