Job interview wear for a restaurant

Mara • Bi // pisces // portuguese
The restaurant is called The Alchemist, its a mordern type of speak easy. Ive seen some people that work there with a retro/hipster look. Im tempted to just wear something casual as its only an interview for a new opening restaurant. Ill be working as a waitress. 
My styles street style so I wanted to wear black ripped jeans, white loose oversized top and a red checked shirt tied around my waist. Green bag to contrast & black heeled ankle boots. Is this too casual or?
UPDATE
I thought fuck it and went with a stripey tunic long sleeved dress and doc martins and accessoried to look hipster af. First to show up and everyone was dressed extremely formal so I felt intimated but I didnt let it stop my confidence. Was the first to be seen. They actually liked my look! I got the job guys!😂👏🏾👏🏾 Thank you for the advice, appreciate it very much!
