TCM is saluting “Pin-Up Girls” every Wednesday this month, and tonight’s lineup includes a 10 p.m. ET showing of that Bob Hope and Bing Crosby road-picture comedy, which takes place in the Far East and co-stars a scantily, and memorably, clad Dorothy Lamour. Ardest feminists may take umbrage regarding the character, the costumes, even the TCM programming theme – but I say, especially regarding the costuming, what’s sarong with that?
