"Oh, uh - " Dan hadn't been expecting the underwear conversation (or mention of it), but that was...fair, he guessed. He maybe flushed a little, just taken by surprise, but was fully confident he could pick out his own boxer briefs, definitely. "I don't claim to the best at the adult thing, but I've at least got underwear down," he grinned a bit. Jesus, he was such a fuckin' nerd sometimes.
But alright - he studied the jeans, checking the tag and as it turned out, Gwen was pretty spot-on with the measurements. He liked to think he was pretty average anyway - he wasn't shaped weird, wasn't all legs and no torso. Women had a lot rougher go of it in the clothing department; he recognized it was unfairly easy for men to find something that fit.
And he was perfectly okay with whatever sweaters Gwen wanted to select. Not picky at all. "It's better than being dead," he replied. "So I'm adjusting okay. I don't really know anyone though. I'll see if I can make friends." Easier said than done?
