I like this casual- perfect for running errands or attending weekend sporting events- type outfit.
I’m wearing my black skinny pants (these are not leggings- these are actually pants) worn layered over a black tank, then a denim shirt, then a black puffy vest.
It’s warm, comfy, and sort of stylish!
On the right, I’m showing a before picture of how not to wear denim! While I love the denim on denim look- this is too much!

I love this idea! Looks great, and looks like it would e easy and comfortable too!
It’s so simple- yet it works! Definitely not high fashion- but cuter than baggy jeans and a oversize sweatshirt.
