Can people tell if you drunk alcohol the night before?

It didn't make any severe changes to my appearance, only causing my face and eyes to be relaxed and my blue eyebags to get darker, yet a couple of people stared at me, also when i walked past them. I even changed the shirt that i was drinking in to a new one to wear today. Can people smell it off your face/hair?
