I have two guesses.

1. They are both members of a secret, Remnant wide criminal organization and they dress alike because that's their uniform/dress code (think of the SPECTRE mooks in From Russia With Love).

2. Neo is an obsessive, yandere fangirl of Romans who he puts up with because she is useful to have around and he's afraid of what she might do if he tells her to get lost (or maybe he's grown to like her despite her yandere tendancies). Or, maybe he's the fanboy.
