First day tomorrow and no uniform

Hey everyone ! I had a question. I had my orientation this past Friday and I was supposed to receive my uniform, but my manager said there’s been a delay. He told me he would contact me over the weekend to give me an update if it arrived. He just texted me right now and said that it’s still not here, but to still show up for my shift tomorrow in black pants and a shirt which he also warned the shirt will get a hole because of the name tag. Has this happened to anyone else ? Is this normal ? I’m anxious at the idea of showing up looking completely different and out of uniform. It doesn’t seem like a good idea. I also don’t want one of my shirts to get a hole in it. I want to tell him I don’t want to start until I get the uniform :/ I don’t understand why they can’t at least give me like an extra shirt since I know they have some because I had to try some on for my uniform fitting. I’m stressing out so much. Any advice ?
