There are some good (common) examples here: https://www.merriam-webster.com/dictionary/outlandish outlandish animals at the zoo an outlandish costume Her book is filled with outlandish characters. She spun some outlandish tales outlandish government specifications These seems the most common uses to me. (Ignore definition 3, it seems old fashioned to me.)

Ah I love this word! So outlandish is an adjective very similar to 'weird' and 'strange', but it is closer to 'eccentric' in meaning. For example, if someone's behaviour is outlandish, they act almost theatrically, like a character on TV or stage. Very over the top and extreme. If someone is wearing outlandish clothing, it may be a bright orange jumper, a crazy hat and black trousers with bright green spots on!
