Drop Down Lists data went selected wont show in the next drop down only remaining data

hello
I am trying to pull data from more than one drop down but don't the same data to show if already use, example as follow:

First drop down Contains:- Pants
Shirts
Hats
Shoes
Dresses

if I chose Hats it should not show up in the second drop down

second drop down Contains:- Pants
Shirts
Shoes
Dresses
Is this done in data validation or combo Box? if so how?

Appreciate any help I can get thank you.

Thanks A lot just what I was looking for.
