The name "Nichols" didn’t mean anything to Draco, but it did to Potter, which probably meant it was some mundane muggle thing.  Then again, she had multiple armed guards and American Aurors show up just to retrieve her.  Perhaps she was from a wealthy muggle family?  Draco had heard that they sometimes hired armed guards to protect them.  Odd that two of the guards were clearly muggles though, and all of their suits were nearly identical.  Draco knew a well-made suit from a poorly-made one, so even from a distance it was clear that while the suits looked good, they were more for function than fashion.
