Good news, I did some alterations and was quite happy with the fit.
Bad news, I didn't get a chance to wear it.
The plan was to go to a socially distant Christmas lunch on Sunday in the dress. Instead I was elbow deep in hot soapy water and cleaning cloths.
I went "up norf" on Thursday to help my daughter move house, intending to come home Saturday evening but it just took too long to move and clean down the house.
Oh well, there is always Christmas day!
