How?
Ill proceed to quote a musing from someone in another forum:
I was reading Ascension the other day and one particular sentence aroused my curiosity. According to the quarians themselves, their environmental suits can hold a weeks worth of bodily waste. I was rather surprised by this, so I turned on my console, popped in ME1, and stared at Tali's ass in-game for about ten minutes.
Her suit is skintight; I don't see any place where a weeks worth of urine and crap could be stored. I could come to only three possible conclusions, which I will parlay to you now:
1. That quarian was lying and they must remove their suits every time they have to use the bathroom.
2. Tali has a different model of suit than most quarians.
3. Those aren't breasts.
That's right, female quarians do not have breasts, they have crap sacks on their chests.
I dont think Quarian physiology makes much sense, considering they never take their suits off. But i certainly don´t imagine them as something even remotely like Human.
