The speaker says the following:
二人ともオメデトさん!コイツ久々に着物新調する言うてエライはしゃいどったで?
He points to his colleague standing behind him who responds with:
今あたしの話はいいでしょう…!?
I find the speaker's line very confusing. Though I've tried to look online I still can't figure out what しゃいどったで means. Can someone explain this to me, I'd really like to know what he's saying here.
