Oh those pants! ... Those shoes! ... That hair!

Sofia Richie pretended she was a bad girl as when she hit up Barneys NY for retail therapy on Tuesday. The actress?/model?/what is she?! hit up the high-priced department store amid reports her relationship with Justin Bieber is an "open door" one.

For the outing, Sofia opted for a "Badwood" cropped army green hoodie (eye roll), baggy black shorts (double eye roll) and white hightops (triple eye roll) as she shopped with a copycat friend who sports blonde cropped extensions similar to hers.

We truly don't get the appeal of Sofia and what the Biebs sees in her ...

But it sounds like she's not the only one he's seeing. Apparently, JB likes dating multiple women at the same time, and has informed his teen love that he's going to keep hooking it up with other ladies, but expects her to stay true to him, an insider told OK.

As long as Sofia is cool with it and the 22-year-old superstar agrees to let him have his way with whomever he wants, she gets to stay on his list of ladies, which includes Kourtney Kardashian, Hailey Baldwin, and whatever Instagram hottie he wants.

While the "Sorry" singer is keeping up his lothario status, he's definitely not cool with Lionel's young daughter seeing anyone else, according to OK's insider. Well ain't that sweet?!

The outlet is also reporting that Sofia is "happy" with the relationship, despite the glaring issues to everyone else. Apparently she's so content with the one-sided set up that she got a cross tattoo, which just so happens to match Bieber's face tattoo.

Oh man ... we see Selena Gomez 2.0 in the making ...

Wanted this cross forever!! Thank you @jonboytattoo your the best
