This question is about dress code.
It seems that dress code is tightly related to Workspace topic as it directly affects one's professional setting.
However, many members downvote the question due to off-topic. There's also a close flag.
Also, Etiquette proposal is about at 50% commitment, and such questions may be on-topic there.
Should dress code and outfit be on-topic here on Workplace?
Yes I think it should be on-topic providing the question deals with the dress code itself, and not the etiquette of when to use it outside of the workplace.
For example, asking what the dress code would be of a particular type of social event is off-topic, however asking what the dress code "business casual" means should be on-topic.
As I said in the question you linked,
I wouldn't close a question as off-topic just because someone was asking what "business casual" was for a social event instead of an interview, and wouldn't close a question that asked what the dress code "Penguins" meant for an interview.
Most workplaces have a dress code, and the phrase "dress code" is almost always used in relation to the workplace, so I think questions about dress codes themselves are completely on-topic here.
The etiquette of when or how to use a dress code on the other hand, may not be on-topic unless the question is also related to the workplace.
Edit: To address the specific question mentioned, no I don't think it's off-topic because it's a question about dress-code, but I do think it could be considered too localized because that dress code doesn't exist, so it is very unlikely another user will ever have the same question.
The problem with the question is not topicality; dress code questions requiring familiarity with the workplace are on topic here.
The problem is there just isn't such a thing as "royal touch dress code". It's not a thing. That's the definition of Too Localized:
This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.
Will this question help future visitors? No. Only people doing to this specific event could benefit from this particular knowledge because the phrase is made up. The meaning is of course implicit, but divining the meaning behind vague, non-workplace related phrases isn't really a great question either.
Take this example question:
I have been invited to a Chili Tuesday at work. What is Chili Tuesday? Will there be Chili or am I expected to provide chili? Is it a pun, implying the weather is chilly as well? Should I bring a coat?
No one can answer this beyond someone at that specific workplace; further, no one outside that specific workplace would benefit from the answer. Even worse, potentially infinite questions of this form can be asked...on any topic. Q: How do you prepare Creme de la creme western yogurt? A: You can't, I made it up. This is not a site for guessing games and divination.
What is the value of questions where the only reasonable answer is "We have no idea, ask your boss/secretary/whatever sent the message in the first place"? Further, what is the value of potentially infinite questions where that's the only reasonable answer?
Dress-code questions about the workplace are on-topic (I agree with Rachel), but that particular question doesn't seem to be about the workplace -- it's a social event, but "people work there" is pretty tenuous. That one should be closed, just as "what should I wear to my boss's wedding?" would be off-topic.
Regretfully Dress Codes are generational topics. The older generations would consider this an On-Topic for the workplace because of the fact that the dress makes the person, and the person dressed well in the workplace makes the company.
Gen-Xers generally see a more relaxed view of this, and loose collars and jeans in some cases are acceptable.
Anything under a Gen-X of age tends to seem to forgo a dress code, or to stretch the limits in some cases of acceptable dress in the work place.
This is my opinion, but also my views of what I've seen in the last 20+ years of being in the work force.
When I first started I was expected to wear a suit. When it hit the late 90's and early 00's it was business causal (Polo and Khakis). Today, it seems a shirt with a button, and jeans are acceptable in a lot of places.
You are going to get some people attempting to keep a dress code but in reality, it comes down to a generational situation.
The younger generations are going to say no, the older generations I feel are going to say yes, but that's my opinion.
For me though, I feel dress code is on topic.
