"...The goblins could probably prove who I am? And they don't, like, talk to wizards about stuff ever."

"I bet Professor Reynolds would wait outside or something, if you asked."

"...Maybe. Yeah."

"Or I could lend you some money, until you can get in by yourself."

"Thanks, but I don't think you're supposed to buy presents for people with their money. I can ask Professor Reynolds..."

Shoulder bump.

Grin.

"Thanks."

"No problem."

Hum.

Of course, Monday's pretty soon after the end of the semester - Anathema arranges for Professor Reynolds to take her in the day after.

Ellie's looking forward to the trip. She's in the Great Hall at nine-thirty on the appointed day.

Professor Reynolds meets her there, dressed in muggle clothes. "Ready to go, Miss Potter?" she asks.

"Yes, Professor."

"Alright."

Down to Hogsmeade Station, then, from there to floo to the Leaky Cauldron - and she assumes Gringotts will be their first stop?

Yes. Ellie needs to withdraw and change a bit of money.

The lines aren't too bad, so by the time they're done with that - and back to the Leaky Cauldron - the assorted muggle shops should be mostly opening. London's pretty big, and her apartment and the Leaky Cauldron are just about on opposite sides - and of course Professor Reynolds is more familiar with what's near her apartment and can actually get them to assorted department stores or shopping malls directly via Apparition, rather than via wandering around and hoping they find something...

Sounds good.

She casts the Disillusionment Charm and a muffling spell over the both of them, explaining both to Ellie as she does so - they'll mostly prevent muggles from seeing them appear or hearing any suspicious noises from the Apparition. And then, with a bit of warning, she moves them to a usually clear space across London - nearby a good sized shopping mall, in fact. Apparition feels rather unpleasantly like being squeezed or pressed down on, all over her body, and her ears pop a bit when it clears.

A bit oof, but overall a convenient way to travel.

Both true.

She removes both charms slowly, so as to make their entrance into observable reality more subtle.

And then: onward to the shops. There's a department store, here, and clothing shops for kids, and a toy store...

She'll start at the department store, see what they have in the intersection of 'shiny' and 'hairclip'.

A good bit! There's pricier, more subdued designs meant for women - generally not much in the way of bedazzling, mostly plain metal with interesting designs. There's cheaper, more tacky designs meant for girls - rhinestone butterflies, colorful sparkly metal ones (though in a plain shape), some shiny plastic balls... Most of the girls' barrettes are cloth bows or flowers, though.

She'll go for a selection of the rhinestone ones, butterflies and cats and birds.

She can find all of those with enough digging.

Excellent. And can she request a box to put them in, suitable for wrapping?

The store certainly has those, nice shiny white boxes in a few different sizes. The cashier smiles at Ellie, asking if she's getting something for a friend.
