is it ever appropriate to wear a gold lamé kittel?

Question

Is it ever appropriate to wear a gold lamé kittel? As far as I know, there were no holidays this weekend (Sept. 9 - 10), but I spotted someone in a pale gold lamé kittel that would have looked more appropriate in Las Vegas than Forest Hills, but what do I know? is there some kind of minhag for when it's appropriate and when not?

Miriam Pratt, welcome to Mi Yodeya. Perhaps what you saw was a Yerushalmi bekishe? — ezra, Commented Sep 11, 2017 at 17:26
@ezra, I've never seen those outside of E"Y, except in Purim photos — Noach MiFrankfurt, Commented Sep 11, 2017 at 22:08
@NoachMiFrankfurt - Me neither but that sounds like what it was! — ezra, Commented Sep 11, 2017 at 23:26
@danny schoemann, it looked more like photo of the Purim costume on the child than an actual bekishe (which is considerably longer than the one I saw). More than likely, it originated in Israel -- I've never seen one here before! Thank you! — Miriam Pratt, Commented Sep 13, 2017 at 14:38

I assume you're referring to men.

It's customary to wear a white Kittel all night and day on Yom Kippur - source Kitzur Shulchan Aruch 131

נוֹהֲגִין לִלְבּוֹשׁ אֶת הַקִּיטֶל, שֶׁהוּא בֶּגֶד מֵתִים, וְעַל יְדֵי זֶה לֵב הָאָדָם נִכְנָע וְנִשְׁבָּר. ‏

Some also do so on Rosh Hashana during the day. (And some wear it all day on Rosh Hashana too)

On Shabbat Chazon some have the custom not wear their regular Shabbat clothes - (ibid 122)

אֲבָל שְׁאָר בִּגְדֵי שַׁבָּת, תַּלְיָא בְּמִנְהַג הַמְּקוֹמוֹת אִם לְהַחְלִיפָן אוֹ לֹא

Any other week one is supposed to get dressed in nice clothes for Shabbat (ibid 72). A gold lamé kittel would surely qualify.

יִשְׁתַּדֵּל שֶׁיִּהְיוּ לוֹ בְּגָדִים נָאִים, וְגַם טַלִּית שֶׁל מִצְוָה נָאָה לִכְבוֹד שַׁבָּת, דִּכְתִיב וְכִבַּדְתּוֹ, וְדָרְשִׁינָן, שֶׁלֹּא יְהֵא מַלְבּוּשְׁךָ שֶׁל שַׁבָּת כְּמַלְבּוּשְׁךָ שֶׁל חֹל ‏
