difference between 2 sentences

w What is the difference between "you looks well" and "you are looking well" ?

There is little difference in meaning between those two.

Both are incorrect. "You looks" is incorrect because we use plural verbs with "you," not singluar verbs such as "looks" with an "s." The second sentence is wrong because it uses "look" in the progressive. In this context, we, as native English speakers, would say simply, "You look good today!" Or, "You look nice today," or "You look smashing!"

"You are looking good/nice/etc" is not wrong. You'll find dozens of examples in the Corpus of Contemporary American English.
