With context I gotta go with Ravenclaw, but the HA has a nice Gryffindor pallette too!

Oh dear on her first year on a dare had experimented with a potion that is too difficult for a student of her academic year and magical potential before the Sorting Hat got anywhere near her head. She's in Slytherin now (and was not the oldest student to be finally sorted since Hogwarts has a long long History), but everyone just calls her St. Mungo's.
The Sorting Hat could not decide between Gryffindor or Ravenclaw, but valued knowledge above courage and chose Ravenclaw.
Slytherin

Slytherin just because the common room is under the lake
: You're pretty sly and cunning, so normally I'd say Slytherin, but you're also a pretty darned smart tactician and good at planning battle strategies, (and frankly you're kind of already in the proper colours for it) so Ravenclaw it is!

Gryffindor. You probably get mistaken for a Hufflepuff fairly often and there's absolutely nothing wrong with that because 'Puffs are lovely but there's just enough confidence and bravery in you to sway the Sorting Hat toward the lion.

Hufflepuff
A gryffindor if I ever saw one.
Hufflepuff
Many people mistake you for a Gryffindor who's brave enough to find and hang out with magical creatures; you're actually a through-and-through Hufflepuff with a knack for Care of Magical Creatures, and an insatiable need to befriend every last thing in the Forbidden Forest.
-Felicius is a Slytherin through and through, although many mistake you for a Hufflepuff. But hey, just because you're cheerful and flighty doesn't mean you can't be ambitious and determined when you're after something you really want!
they/them/theirs, please.
Most certainly a Gryffindor. Your battle scars and proud tattoos are proof that your courage in the face of pain is outstanding, Few are those who can dare to fight in such a long dress, yet you welcome the additional challenge and trust in the aim of your shield and the strength of your blade to keep you safe.
