is it okay to wash colothes with handsoap?

yes. my nan used to use sunlight soap on her clothes

Yes--if and where necessary.

What are "colothes"?

Poor trolling attempt. It's spelled "clothes". To answer the question, you "could" use it I suppose, but why not just use laundry soap/detergent?

Of course, it's possible.

Moron, or troll?

Troll, or moron?

So hard to tell the difference sometimes ...

Ive used dawn dish liquid with no problems

It isn't going to hurt the clothing.  The problem is that the soap probably isn't as concentrated a detergent and it will create a lot more suds. You have a lots of boggles and your close won't get as clean.  

It's how people used to wash their clothes a long time ago, nothing to be worried about.

If you are washing in the sink or a wash basin, soap is fine--just work the soap until you see lots of suds.  Be sure to rinse out the clothes thoroughly.

Handsoap won't work very well in a washing machine.
