HELP is this outfit appropriate for a Target Interview

Update: i got the job! 😄thank you for all of the comments!

Does this look fine? Should i tuck in the shirt? Or do something different with my hair? I will make my hair in a neater bun but thats basically the position i plan on putting it in. I have an Interview for Target tmrw afternoon and I’m a little but nervous because i don’t know what to wear. My options are very limited and i don’t have very many clothes to wear for this occasion. I am 18 and this is my first interview. These are my sisters clothes too.

Also i will be wearing black basic flats
