Sanctuary of Truth — dress code and worth it?

Worth 2–3 hrs — all-wood carving temple Naklua north, ~500 baht entry, modest dress shoulders/knees (sarongs rent). Guided tour included some tickets. Photos stunning outside and in. Not a working wat — art monument still building. Morning less tour buses. Grab from Jomtien 150 baht. Combine Naklua fish market lunch. Skip if tight budget — free Big Buddha viewpoint alternative.
