Be clear about your style in Kourtney's Gianvito Rossi heels

She's recently returned from a wild girls' holiday in Mexico where she donned a variety of party dresses and skimpy swimwear, but today Kourtney Kardashian went for an altogether more low-key look as she made her way to church.

Perspex heels have dominated the footwear scene lately, and Gianvito Rossi were one of the first designer brands to pioneer the look. We love the fresh modern twist on classic stilettos and it's no wonder everyone from Allison Williams, to Nicole Scherzinger, have been spotted in a pair.

The couple split in 2015 after photos of Scott with an ex surfaced.

Scott was reportedly stung when he saw recent photos of Kourtney with her rumored current beau Younes, according to sources who spoke toTMZ.

To hear the TMZ sources tell it, Scott's take is that he was led to believe that if he managed sobriety and 'respect,' Kourtney might consider taking him back.
