Question

Answer

You wouldn't use #1 because that is more appropriate for a pair of pants than glasses.
#2 is fine.
#3 is ok, but what I would say is "..how they look on you".

Answer

"How...look like" isn't the phrase we use in English, so unfortunately all of your examples are incorrect.

We use "how do I look?" to ask if our appearance is nice and acceptable. Don't confuse it with the phrase "what... look like" ("What does she look like?"), which simply talks about appearance in general - no value judgments.

After removing "like" from your examples, the best option is #3: "You should put on those glasses to see how they look on you." It's pretty simple really - you put, or have, glasses "on".
