Being Christian does not mean you have to deny any sense of aesthetics or have to lack personal style. but I would counsel to make use of the discernment being born again brings. My own “style” is to juxtaposing abundance with elegant minimalism, exploring the quirky and applying it to the fulcrum where ascetic meets aesthetic.
“All things are lawful for me, but all things are not expedient:
all things are lawful for me, but all things edify not.”
– 1 Corinthians 10:23 (KJV)

(remember, not everything will be edifying – use that discernment!)
