Leave it to Megan Fox to make a cardigan look Sєxy

This isn’t your grandma’s cardigan.

Megan Fox stepped out in Los Angeles over the weekend, putting a typically Sєxy spin on an ordinarily conservative closet classic.

The “Transformers” actress, 35, looked red-H๏τ in a crimson Jacquemus cardigan ($410) that, while held closed with a delicate gold logo charm in lieu of a ʙuттon, fit right in with this summer’s skin-baring single-ʙuттon trend.

Fox skipped a shirt underneath the sweater, pairing the knit with a matching pencil skirt ($605) featuring sultry waist cutouts. She finished her flame-hued outfit with a red Mietis mini bag ($660 and Femme LA stilettos ($189).

The look was somewhat reminiscent of the similarly scarlet getup Fox chose for her birthday dinner date with boyfriend Machine Gun Kelly in May, comprised of a cherry Alex Perry pantsuit styled with a matching bra rather than a shirt.

The brunette bombshell is famously fond of itty-bitty tops, having been snapped in everything from a long-sleeved underwire look to a soft ribbed bralette — the latter paired, incidentally, with a coordinating cardigan.

No word on what “Cardigan” songstress Taylor Swift thinks of Fox’s take on her favorite knit.
