Can you contract herpes through sharing underwear?

No risk, no worries: Of course another person's underwear should be laundered before wearing. But maybe you accidentally used a roommate's panties instead of your own? But still no risk; genital herpes has never been known (or even suspected) to be transmitted by clothing, even if the other person had an active outbreak of GH. It is caught only by sex with infected partner. Don't worry about it.
