it depends if they give u bachelor accomodation then in that flat there are only 2 rooms 1 kitchen 1 bathroom n 1 toilet.but i dont think so that they will give u bachelor accomodation cuz lots of teachers who are single they live in C type flats.which has 3 bedrooms 2 bathrooms 1 laundry 1 kitchen,drawin room n living room.

and as per ur concern about dress code u can wear anything u like.its not that much conservative :P
