prefixing DTO / POCOS - naming conventions?

simple question really, i was wanting to know what naming conventions anybody puts on there DTO / POCOS ....

I didn't really want to prefix like hungarian notation.. i got away from that!.

But my dtos naming are clashing with my actual returned object names and although they are in a different namespace its still a bit confusing..

I was wondering what naming conventions anybody applies to it

for example my customer object is called Customer

and i do a mapping to dto ... which is Customer.. iwas thinking DtoCustomer ..

Not sure

Anyone ?
