I agree that everything you wear definitely looks a lot better when you have a bra on. I'm really into sports, by the way, and I can assure you that women who are size A (like myself) still need to wear sport bras. I once tried doing a workout without wearing a bra and it felt really uncomfortable.
Well, while not exactly the same, I have somehow similar experience
Bare feet
As most of people I usually walk in shoes/boots, but sometimes during summer vacation when visiting parents on countryside I go for a few weeks without footware (mostly), and it feels "uncomfortable" only for first week
Later you stop noticing it and after vacation it feels "uncomfortable" to wear shoes
Hell, in high school at the end of summer I could run over freshly harvested wheat field without any pain
How it relates to bras?
If you tried going without bra only once, of course you would feel "uncomfortable", but I can assure you that if you tried this for couple of weeks or months you would notice that it isn't that bad.
For example I'm pretty sure sweating would be less of a problem without bra (or any clothes at all)
