Ebay - Why no tags on new items? Fake or not?

[~ Mhmmmm ~]

I understand when someone is selling something they bought and say never wore and just didn't keep the tags. But what about sellers that have a big amount of the same item, why is it new without tags?
For example this lady sells Victoria's secret hoodies - lots of the same one, lots of colors and sizes, yet they don't have tags. Does this mean they are fake? I was also wondering how these sellers get so many of these items in bulk. I mean where do you buy Victoria's Secret wholesale? Or is it fake?

Here is the link please check it out and tell me what you think.

I was also wondering if there was any way I could check somewhere to see if this specific item was ever sold at Victoria's secret because if not it would be fake. Does anyone know if Victoria's secret sell stuff exclusively on ebay or anything like that?
