Porsha Williams -- Most Glam Mug Shot Ever

Porsha Williams is gonna have bitches clamoring for jailhouse makeovers after they see the mug shot she just took in Atlanta.

TMZ obtained the mug shot -- taken with full hair and makeup -- when the "Real Housewives of Atlanta" cast member turned herself in to the Fulton County Sheriff to be booked for simple battery ... a misdemeanor.

As TMZ first reported ... an arrest warrant was issued for Porsha stemming from the brawl she had with Kenya Moore while shooting RHOA.

Porsha was released immediately after posting her $2,000 bail. She paid cash.
