What's your favourite nightwear?

Dear Friend, I like to wear cotton wears in winter seasons asw it gives warmness and have good feeling. Where as in summer, i like to have less clothes i.e. only inner-wear.So my choice is vary from seasons to seasons. Similarly Some times it also depend on company.So my choice is vary for person to person i.e. if i feel Insecure then I like button Payjamas which is well protected. But usually I like to have cotton wear

i like pajamas..

in summer i prefer to wear just shorts or no clothes...otherwise i wear shorts n a thin cotton tee..
