Do Japanese clothing stores have to stick out their thighs?

Nowadays, Japanese restaurants are very popular. They are not like the Great Hall of the People. They are just places to eat, and there is no rule about what clothes to wear. They are just good places for you to enjoy food, have dinner with friends and chat. You can wear whatever you want. As long as you don't wear a mix of pants and slippers, you won't be surprised what you wear!
