Link hadn't forgotten about the head scarf and veil for Zelda, he'd just gotten forcibly sidetracked by an extended makeup lesson. So while the woman went through what was probably going to be a long and tedious process of writing and adding, he headed back over to the clothing to see what she had- if anything, and oh lady, she'd better -on that front.
And take the time to retrieve his fake wallet from the Slate. He eyed the prices listed for just the clothing and realized he was probably walking away with a price tag of a couple thousand rupees less than he'd been expecting.
Now he really felt bad about accepting that makeup she didn't want to charge him for.
There didn't seem to be any variety in the head scarf and veil sets, so with a mental shrug, he grabbed one at random and took it back over to the rest of his purchase.
