You can reuse those things? They come in a plastic bag. I always thought theywere disposables.
Wear the socks fresh from the bag. Wash your new underwear before you wear it.
Wear both socks and underwear straight from the bag. They are so full of pesticides and preservatives that you can wear them two or three times as long as an old pair of socks or underwear!
With socks? New? Old? Washed? Unwashed?
Aaaahhh, that new sock smell! 
I opened this thread to find out how 24 people could have differing opinions on such a simple question. I must say, it was worth the effort.
Isn’t there an old joke? Put two Dopers in a room and they’ll form three political parties?
No, no, no! Wait until they have holes, *then *wear them inside out . . . so the holes are on the inside. They last twice as long that way.
Regarding your immediate question: Either way, you’ll be removing the socks from the bags. What are your plans for the bags, and will you wash them first?
You know, this thread seemed awfully familiar.
And so did your username.
The two seemed familiar together.
Then I remembered.
You’re the guy who needed instructions for his bed.
Personally, I can tell you that, 4 times out of 5, I buy socks (and underwear, for that matter) for the specific purpose of pushing back laundry day.
Which, of course, would mean that I don’t wash them after purchase, otherwise why bother purchasing new?
I got my eye on you, featherlou! You’re an “Ideas” gal.
Son? Is that you?

Sock it to me?

Throw them away. Bulk socks sold in large plastic bags aren’t worth the $4 you threw down for them. Get you some tech socks, something like the dri-fit ones Nike makes. They last longer, stop sweat from wrecking your shoes, and treat your tootsies better too.
Please tell me they’re not white gym socks though. No man should wear white gym socks, ever.
Because purchasing used socks is disgusting, maybe?
Bosda, don’t be afraid to come back if you need help opening the bag!
Remember that there are TWO bags. There will be an important choice as to which bag to open first.
Very serious stuff.
I think I like Bosda - he makes me feel all decisive. 
My husband wears techhie-type socks. We buy them on line to save a few bucks. I think they run about $13/pr. He loves them. And they’re always gray; never white. That’s just wrong unless you’re running or something.
That’s right, baby! I got a million of 'em!
What are guys supposed to wear with their athletic shoes if not white gym socks? Their black dress socks? Heh. That’d be funny.
Whadda ya talkin’ about? Everybody knows black dress socks are for sandals.*
- FYI, I just bought 10 pairs of black dress socks, 'cause the launderer lost about 12 pairs en masse. I ain’t washing them first because, well, now I’m paranoid.
If I were verrry wealthy, they would be disposable. I would wear a brand new pair of socks every day. Ahhh…new cushiony socks.
Yeah. In Florida!
