Answer:
What type of dress can never be worn?
I have a hundred legs but cannot stand. I have a long neck but no head. I cannot see and I help keep your house neat and tidy.
you can throw me away but I will always be coming back
I fly away as soon as you set me loose. People around you may slowly move away once they sense my presence.
I fly to any foreign parts assisted by my spreading wings. My body holds an hundred hearts Nay I will tell you stranger things when I am not in haste I ride and then I mend my pace anon.
No matter how little or how much you use me, you change me every month.
