Don't limit the slipcovers to the living room. Slipcovers extend to these dining chairs, upping the Belgian quotient in this kitchen. The palette, the wood countertop and the window casements also bring in the style.
I like the monochomatic colours and the mix of old & new finishes. One interesting idea of covering kitchen chairs is that they could be extra dining room chairs which the coves protect from grease and spills. Note the shutters keeping out the sun's direct rays.
