Please bear with me as I'm eagerly working on releasing all the stuff. I have a whopping 220 files to wade through (and that's without meshes, yes) and pack in to little christmassy gift collection files, so I have absolutely no idea where to start! There's the dungeons, the Great Hall, the dorms, the common rooms, the class rooms, the hospital wing, the library aso....HELP!
Anyway, if you're one of those people like me who always kind of thought "Gosh, a Harry Potter neighbourhood that would be rad, but where do I even start??" here are a few links that helped me tons while building my own Hogwarts:
I really love this suit with the jacket by Yuxi in combinations with one of Daislias Hogwarts scarfs! (they're adult only obviously, my students are YA since I built Hogwarts as a university)
Chaz' Hermione has a neat Hogwarts sweater/tie/shirt combo included (I'm not very talented when it comes to Bodyshop, but I should tackle this thing at some point and make it unisex and in all house colors)
If you've got all these things you are basically ready to go, but keeping an eye open for sets with little knick-knacks that could be useful and potentially magical is a must! ;)
Then there's always the difficulty of actually building Hogwarts. Lots of people have managed to do so, I tried to build my own, more or less successfully. I wanted to have it as one lot without my laptop crashing and burning, so I had to scale down a bit. It's not perfect, cause I'm horrible at building but it does the job (the entrance to the Slytherin common room is through the potions class room, cough, haha). Personally, I would give it a try and build it to your likings and at a size your computer can handle, otherwise have a look at the ones I linked.
Alright, bye for now, I'll hopefully have the first set up next week, so stay tuned!
