Too bad we can't get too see what she's working with under there. Ash got a boobjob and a new haircut in the 3rd, can't let that go to waste.
You can see Tali in ME3, she leaves a picture of herself up in your room for you later on in the game.
Sadly, it's a stock photo that you can find on the internet years ago that Bioware horribly photoshopped, instead of actually designing her so that they could save money and cut corners like they did with Dragon Age 2. Quite pathetic.
