My goodness, the NYT is getting edgy nowadays! Even risque, you might say. It's a cute revealer, with BOOBYTRAPS, and the first word in each themed answer goes with the word "bra" to name a type of brassiere. On that level, it's fun. I'm not sure about 47A: Be dead and buried, in slang (PUSHUPDAISIES). Seems to me that the term is "pushing up the daisies", which obviously wouldn't work for the puzzle. Unless somebody has a pushing-up bra. Anyhoo. I find it somewhat disappointing that all three types of bra are essentially the same thing. No "sports" bra, "strapless" bra, um...
Because there are only four theme answers, the puzzle feels open and unforced, for the most part. 1A: Place to swim (POOL) is straightforward and unobjectionable. I'll give it a C. The long down answers are similarly not terribly inspired, but not problematic. I liked 41:A Add more to, as someone's drink (FRESHEN).
I'm not fond of ODIST, SYS, or SYM. I felt that SLiLY is more correct than SLYLY, but I could be wrong about that. There were a number of brand names as well. Still, it was a pretty smooth solve over all.
My favorite clue-answer for the day is 30A: "Plan 9 From ____ Space" (OUTER). I've always enjoyed Ed Wood's work. Second place went to MYST, a game I very much enjoyed in the early 1990s.
