Hint of Shimmer

Paired it with the Ralph Lauren Navy pleated skirt for a Chanel-esque inspired look. It has just the right amount of interest with shimmer but formal enough for the office

Perfect to throw over the shoulders. Gold buttons and has a little glittery touch within the knit. Great navy blue cardigan

Team RTR Review

would say overall this fits a little small, wore with a navy tank underneath because it was tight across the chest and the buttons were gapping. arms also were a little short for me, but subtle sparkle in the knit is very cute.

Classic classiness

Material feels synthetic like the kind you put in the wash and just comes out dry bc it’s all plastic. (Which is crazy for these $$$ brands to be selling!) anyways, the fit is nice and fabric is thick so good for fall. Looks super classy & instantly elevates the look

Photos don’t do it justice

The gold details in the knitting of the fabric and the gold buttons add a hint of charm to an otherwise basic sweater. Very comfy. Not itchy. Warm. Great for everyday wear and work.

Everyday with some flair!

Generally am m/l with a larger chest and this was not a generous xl but fit nicely. Was able to wear buttoned up. Super cute, wanted to buy! Thicker slightly spongy material. The buttons give it both extra flavor and a Chanel/classic vibe

One of my favorite rent this month. The sweater had just enough sparkle to feel unique without being too flashy. It was a classy and quick way to build a look. I would love to own this one and I will definitely recommend it.
