sonenki = dress (noun) (some things Google found for "sonenki": a rare term; user names; a Japanese term for people in their 50s to early 60s; the similarly named Soninke people live in West Africa around the area of the former Ghana Empire)
Word derivation for "dress":
Basque = soineko, Finnish = leninki (dress or frock)
Miresua = sonenki
This is the Miresua conlang word for the women's garment, as opposed to clothing in general, attire or costume.
The Basque word jantzi can mean a dress. The Finnish word mekko also means a dress or frock, but it's not in my physical (not online) Hippocrene dictionary.
