Hi - you look perfectly presentable for this type of job. No one expects you to look amazing, they just expect you to look like you care and can read the appropriateness and seriousness of the situation. I think this satisfies that.

Hiring Managers are people too, if you're questioned on it and feel comfortable I might explain some of the reasons you provided here. A good manager will hear you and be quite reasonable about it. The ones that don't understand are going to be a bit toxic.

Good luck!
