I could be wrong but It looks like a dress from a creator who went behind a paywall patreon. She had some really nice things and a lot of clothes that looks like this. But there are similar dresses for free
This first one is behind an adfly link. I have all kind of ad fly skippers but letting you know because some simmer don't like to click on adfly.
Thanks for the link! I knew in my heart it was her!😆 I looked through some of her stuff but everything I clicked took me to her paywalled patreon so I gave up looking for this dress.
If it helps, you could do a search for children's "acc shirts", to find shirts that can be layered with a jumper. Then look through them to see if you could find one with stripes.
