Other forms: pseudoclassics
The word pseudoclassic describes something that mimics a classical style but lacks substance. Pseudoclassic columns in the style of Ancient Greek architecture might look like solid marble from the sidewalk, but if you tap on them, you'll probably find that they're actually hollow plastic.
While a high-quality revival of the styles of Ancient Greece and Rome would be considered neoclassical, the term pseudoclassic (or pseudoclassical) typically refers to things that are made to seem classical in style but are really not substantial or "real." Rather, they are usually superficial or just plain fake. A good way to remember this nuance is to remember that pseudo- means "false" or "fake." Whether it's a modern building with tacked-on Greek pillars or a statue made of painted plaster meant to look like ancient stone, if the classic style is just a cheap costume, it's pseudoclassic.
