How do people come up with these themes?! Today's FASHIONPOLICE wardrobe - featuring a DUSTJACKET (17A: Proper attire for taking fingerprints?), a TRAILBLAZER (24A: ... for picking up a series of clues), the hilarious HOLDINGTANK (50A: ... for detaining a perp?), and a FOLLOWSUIT (59A: ... for shadowing a suspect?) - is so absurd! But it hangs well and the fit is pretty snug. :) I've got to hand it to these constructors... always tugging at phrases, turning them over and inside out, and tailoring them for other uses.
In the non-theme Across answers there are only two above five letters, the opaque-to-me AARONS (29A: Hicks and Judge of Major League Baseball), and TRAUMA, which, ironically, I enjoyed.
The Down answers, on the other hand, included a slew of sevens, eights, and nines. My favorites were the non-airport-coded LAGUARDIA and DSTUDENTS (31D: Ones far from the honor roll). Hah! I did a double take when I saw it starting out with DSTU, but I wasn't worried for long.
I'm not sure how I had never heard of the RARITAN river before, but I'm glad to learn of it now. As for EMERSION (39D: Reappearance above water, as for a submarine), well, I think I can go on pretending I had never heard of that without getting into too much trouble.
Overall, I was amused by the theme, and there's plenty of bonus fill. Thumbs up!
