What do samurai's look like?

"Samurai" was a hereditary title, meaning you were born into a samurai family and had no choice about becoming one. If not born samurai it was essentially impossible to become one, as samurai status was something that was given or taken at the will of the local daimyo (lord). And since the title and its associated benefits was considered the highest honour, the title was given to non-samurai families extremely rarely.
