That England are the opponents only adds another layer to a historic fixture and the Manchester City midfielder is optimistic her side can capitalise on the excitement surrounding their maiden tournament.
Shelley Kerr’s side dropped points only once in qualifying and will face Argentina and Japan after the Lionesses in Group D.
And whilst she holds a belief Scotland can make an impact in France, Weir knows they will need to be at their best throughout.
“We’re realistic in our expectations but we’re also confident in the squad we’ve got,” she said when speaking to her home town media before the tournament.
“Our aim is to get out of the group. We know that’s something we can achieve with the squad we’ve got.
“We won’t look too far ahead but that’s definitely our number one aim.
“There’s so much excitement around our squad at the moment, so it is a really exciting time to be part of, and a proud moment.
“Hopefully, we do the country proud.”
After bowing out of the Euro 2017 group stage on goal difference, the 23-year-old says Scotland must make the small margins count if they’re to progress this time.
Weir, who scored five times in her first season with City believes they've learnt from the experience and are in a much better position now.
That's not merely due to the pool of talent, with the Dunfermline native praising the work ethic and passion of her team-mates.
“What’s great about our squad is that we all work so hard for each other and we’re all so passionate about representing Scotland well and doing a good job, especially as it is our first World Cup,” explained the domestic cup double winner.
“The campaign was difficult at times; we really worked hard for it and needed the full squad.
“People popped up at different moments to get us across the line and our aim when we set out was to qualify.
“That’s done now and our focus for this whole year has been the World Cup.
“We’ve tried to enjoy it but, at the same time, putting in good preparation to go out there, make something happen and not just make up the numbers.”
Scotland face England at 5pm (BST) on Sunday 9 June and in the UK the game will be broadcast live on BBC One.
