Ross: Ok, um, basically you wanna use one machine for all your whites, a whole nother machine for colors, and a third for your uh, your uh, delicates, and that would be your bras and your under-panty things.

Rachel: Ok, Well, what about these are white cotton panties？ Would they go with whites or delicates?
