a women's get-together; a social gathering (meal, drinks, etc.) exclusively for female friends, usually informal.
今度の土曜に友達と女子会を開く予定だ。
I'm planning to have a girls' night with friends this Saturday.
女子会ではスイーツをたくさん頼んで写真を撮った。
At the girls' gathering we ordered a lot of desserts and took photos.
職場の女子会は毎月開かれている。
The office's women's get-together is held every month.
昨は久しぶりの女子会で昔話に花が咲いた。
Yesterday's girls' gathering was the first in a while; we had a lively chat about old times.
