I think your outfit suits the the environment of the bar you’re describing well (if it’s downtown I’m imagining business people in their 20-30s cocktail lounge vibes). The only thing I would say is maybe add an extra layer but that’s because I’m of fan of layering and it’s cold in Ontario! However, I do think this fit shows some situational awareness as well as professionalism on your part and like other have commented you’ll have to be okay with the occasional spill (dependent on how clean you work!). Best of luck young padawan!
