IKEA has a variety of gray cabinets like LIXHULT cabinet in steel with gray powder coating. The cabinet has two doors and can be stacked or used with or without legs. Put your favorite things on top to make a stylish focal point.
Note: The style of pants— Can tuck any nice shirt under it. Tuck casual shirt and wear blazer. The shoes— They look comfortable, wearable to work. It could be done with flats as well, not to as potent an effect I think.
