Oversized sweaters are a pretty casual look. A nice roomy sweater gives you the comfort of pajamas without the stigma of wearing them in public. That being said, it’s totally possible to dress this trend up. The key is to counter the casual chunkiness of the sweater with a sumptuous luxury fabric, such as silk, satin or chiffon.
By the way, mixing casual with formal is an easy way to make an outfit look more creative. And frankly, it’s a good reason to actually buy that party dress or satin pants you might find while thrifting but have no idea where you’ll wear it. Pair it with an oversized sweater and wear it to work!
