Wales and Italy’s match will be followed by the Welsh Rugby Union’s national women’s finals day, with teams contesting the cup, plate and bowl competitions.
Wales head coach Ioan Cunningham said it will be a “celebration of rugby for women and girls in Wales”.
But he says all their focus will be on getting the bonus-point win, which is the least Wales need if they are to avoid finishing last.
“It is focusing on our performance and not letting the occasion or the venue get the better of us,” Cunningham said.
“We have to win, it’s as simple as that, we’ve had a short turnaround from the France game and it’s basically ‘how can we win one game of rugby?’
“That’s what we’ve discussed as a team and hopefully we can put it on the pitch on Saturday.”
