Sounds fine BUT if by slinky you mean satin or silk charmeuse in a light color, be very, very wary of cameras. Things that look fine in motion to the naked eye can look appallingly horrible when freeze-framed in a picture. A photograph can make certain slinky outfits look way less appropriate than they looked in person.
nottelling, I am dying after reading your post about the 80s party! LOL. It reminded me of a scene from a really old movie about Lord Byron… IIRC, there was a scene where Lady Caroline Lamb showed up looking totally ridiculous at what supposed to be a costume ball… except it was not.
For slinky yet appropriate, I highly recommend Herve Leger dresses. No need for Spanx underneath, and the dress will not let you overindulge in vino and tasty appetizers. 
That is hilarious, nottelling.
You can still be dressed up and attractive without being slinky.
I’m a teacher in a Catholic school, so my answer may be skewed.
But anything I do at work is still at work. So I dress and behave with an eye toward being at work.
So, no, I wouldn’t cross the line into “slinky” at any sort of a work function.
Slinky and work don’t mix, whether it’s a party or not. Work parties are not the same as purely social functions.
The difference might be if the party were black tie. The “WWMOD” rule applies to an event where her husband and every other man was in a tuxedo. For truly formal events, slinky and formal dress is fine.
If the men are in suits, the women should dress at the same level. Unfortunately, if it’s a work event, it’s work.
(Loved the Los Cabos story !!)
Finally! Something for the man with no taste to wear to the company holiday party with his slinky-outfitted date:
I think both of these dresses could be described as “slinky” but the length saves them. If cleavage was in check I could see wearing both to a holiday party:

I throw a big bash every other January. …dinner, open bar, and include the hotel. The outfits have paled in comparison to some of the behavior. One young staffer behaved so inappropriately with my husband and my administrators husband at the event he had to have a discussion with her the next week at work.
I have a deal with myself that I have never broken. At any work related party/dinner or any social event relating to my children’s school, I never have more than 2 drinks. After that I quietly order ginger ale in a wine or champagne glass.
When in doubt about an outfit for office or an office party, I’d opt for conservative. I don’t really want my office to remember my attire long after the party.
HarvestMoon, great deal! I have (relatively recently) been to a party where a bunch of law interns got so stoned, it was scary to watch them hobble around on those spiky heels! Eek. I have no issues with walking around with a glass of sparkling water. As long as my dress is slinky and sparkly, no one is going to focus on my glass.
@HarvestMoon1 , I do the exact same thing.
Both of those look like LBDs to me. They can go just about anywhere.
On another note, it’s nice to see what well-behaved, good boys and girls we have on CC.
Those dresses are remarkably untrampy for Bebe
I would never, ever, ever wear a slinky outfit to an office party. (And yes, I’m still fit enough to pull it off). Wouldn’t even consider it. Women have a hard enough time being taken seriously at work, and if you’re lucky enough to be valued for your talent and intellect why make it harder on some younger woman who is still striving to prove herself?
@GMTplus7 I have always viewed Bebe as geared toward the teen and early 20’s crowd. Most of their line is skin tight and too short for women. Every once in a while they come out with something more conservative.
My point with the Bebe dress was that even tight clothing can be appropriate for a corporate party if the length is right and there is sufficient coverage on the top. I think there is a lot of territory between defaulting to a suit for a corporate party and wearing something inappropriately slinky.
You misspelled “sophisticated sexuality.” 
About 20 years ago I wore a black leather miniskirt with a black top and heals and dark thick hose to a fund raiser black tie event. I looked great- did not regret it- got the approval of H and the D’s. Nothing stuck out or showed and I have a photo from the evening ,that was great too. It was almost a star trek look with the leather keeping all nicely in without movement. Not slinky but risque.
Would u wear slinky to a non company sponsored social event where there are likely to be many co-workers?
I went to a St. Andrews Ball last year. It was funny to see so many guys I know professionally, wearing kilts.
My questions to the folks who say yes to the original question- Are you trying to meet someone? No? Just trying to look good. Well, everyone sees you most work days, so they probably already have an opinion about your looks and dress.
My point is, ask what are you trying to accomplish? Is it to be sexy? Then ask yourself if this us the appropriate venue. Is it to attract someone? Again, same question.
Basically, work is work. And a company party is still work.
