How to create 4 effortless looks with a cozy 'boyfriend' cardigan sweater

Start with a cozy oversized cardigan, like this boyfriend style from Gap. It's available in five neutral colors, including cozy brown, which is ideal for fall.

For an effortless daytime look, pair your cozy oversized cardigan with a fitted first layer. Try this long-sleeve square-neck bodysuit from Everlane made with 92% suprima cotton. 

Keep it casual with a straight-leg jean, like this popular style from Abercrombie and Fitch. This wash will work in your closet year-round.

Finish this look with an easy walking shoe, like a pair of on-trend loafers. We love this pair with its rich saddle color. 

For a pop of color, add this Rare Beauty lip balm in the shade Support (a beautiful plum brown).

For a night out, pair your cardigan with this corset midi sweater dress to create a classy yet comfortable ensemble. 

For a little lift, add a pointed-toe mule like these by Jeffrey Campbell. We love the studded detail for a little extra flair. 

A little black bag is a must for fall (and every season, really). Try the leather Sydney Clutch Bag from Madewell with this look. 

Don't forget to accessorize! For a night out, we love these puffed hoop earrings.

For a go-to office look, start with another closet staple: the white button down. Layer this under your cardigan.

Add your cardigan over your white button-up. Then, add an oversized blazer over the cardigan for a multi-layered look that's sure to impress. 

While we love a classic black trouser for the office, we also love the idea of a black jean to complete this look. This particular pair is high-rise to accentuate your waist and made from organic cotton with a "touch of stretch," Everlane's website explains. 

Add a pop of gold with this toggle chain necklace. It's the perfect accessory to wear layered or on its own. 

Of course, a good work tote bag is key. Try this one from Beis, featuring flat shoulder straps with full zip closure. Plus, there's a removable interior zip pouch, a large zip pocket, and a padded laptop sleeve pocket among other details. 

Did someone say "matching set?" Luckily for us, the Gap boyfriend cardigan has a pair of matching sweater pants. We love the idea of pairing these with the cardigan for a day of travel, whether it's a road trip or a long flight. 

Pair your sweater ensemble with these trainers with an upper made from 100% recycled nylon. Plus, it has a metallic leather heel and a cushy gel insert.

Accessorize this cozy look with some extra warmth: we love this Barbour scarf in its herringbone weave pattern.

Layer a cashmere tee like this one from Quince under your sweater. It's made from 100% grade-A Mongolian cashmere and we guarantee you'll be able to style this year-round.
