I would say wear a nice, professional-looking outfit. You always want to make a good first impression, even when you are just turning in the job application. Some people are interviewed on the spot when they turn in a job application or go to apply for a job. That happened to me once. You may not know who you are giving your application to. You could be giving it directly to the hiring manager or a supervisor and you will not even know it at the time. So it's a good idea to wear some type of professional/business attire, even when you are just turning in the application. You can try something similar to these outfits:
Doesn't matter. You might get an interview when you apply and when you apply is when you are making your first impression, not the interview. Always be prepared by dressing nice. Wear a blouse, long black wide leg flowing pants that drag on the floor and tall high heels. Also, hair back, full makeup and acrylic nails in a French manicure. Good luck!
Anything is fine, as long as you look clean and neat. It doesn't have to be smart, just make sure nothing's creased or dirty and you look presentable. I've always worn jeans. You're only going to be there for a minute and they're probably not going to pay much attention.
Wear what they sell so they know you're interested
