"Kimono" refers specifically to the robe, though, not the full formal costume. I don't know if there's a word for the full set of formal clothes that goes along with a kimono. (In Lojban, I suppose it would be "ponta'ugri".) If you need to say "kimono", you can say "ponpastu", "Japanese robe".

Technically, "stici" has nothing to do with western culture, only with the direction "west", so its use in this sense is metaphorical. Also, I can attest that "western" suits are worn in Japan, among other places. Maybe "brito" instead, in reference to the origin of suits?
In any event, in most contexts "loi lityta'u", "lo ta'ugri", or even "loi taxfu", can be used with little chance of misunderstanding. When more precision is needed, the extra descriptors can be piled on. I don't think a new gismu is needed, unless you're a Lojbanic tailor. :)
