...Right because Shep totally can't be an adept, engineer, sentinel, infiltrator. Nope restricted to one class.
An adept Shep, engineer Shep, sentinel Shep, infiltrator Shep, vanguard Shep, etc is still a Soldier. I didn't mean to imply the class... just their status in the Alliance Military. Shepard is a soldier... in any conceivable capacity. A warrior who fights for the Alliance, later a Spectre that fights for the Council, and eventually a hero who fights for everyone or whatever... but always a Soldier.
If your excuse is that a civilian's clothes are suddenly as protective as military armor I'm not sure what to tell you...
And your biotics excuse would work for the Adept and Sentinel classes. So no those Sheps wouldn't have to wear heavy armor...and yet they do...? Maybe because it's more protective than wearing skin tight clothing? Just a thought. 
Hell Shep can be a better biotic than Miranda on par with Jack and he/she still wears armor.
Armor doesn't matter.
Cloths denote character... not functionality. Shepard wears armor because it is appropriate for him/her to do so. Most of the other character do not wear any armor into combat because it doesn't benefit them... or something.
Miranda fights in a cat suit.
Jack fights half naked.
Jacob fights in what appears to be the same material as Miranda.
Kasumi fights in a cute thieves outfit.
Tali fights in a suit that if it gets torn by a bullet then she can get an infection and die if she isn't careful.
Mordin fights in... whatever that is he's wearing...
Thane fights in a trench coat and slacks.
Samara fights with half her chest in the free air in a cat suit similar to Miranda's.
Legion fights naked

Garrus, Grunt, Shepard and Zaeed are the only ones who wear armor... They're in the minority.
