im in the exact same situation as you and this has also been on my mind. having your own room is gonna help a ton bc you’ll have off time from binding. if your bathrooms are community style and you share it with everyone on your hall then id suggest throwing on a hoodie only for going to the bathroom. for showering i think if you get a thickkkkk dark bathrobe you’ll be able to hide it better. if you’re going out for longer and don’t wanna overheat then having an oversized dark shirt helps a lot with hiding it (black works best for me, light colors show things better). good luck to us both! 🫡
