Basic, yes. Necessity, no.
I end up rarely ever wearing pumps. I seem to go straight from sandals to boots and back again, and in between I usually like my flats -- loafers, ballet, oxfords -- and my pumps go mainly unworn.
I cannot get excited about nude pumps for me. I have some metallic ones that suffice and have a bit more edge. Those suit my current style and needs better than nude pumps.
I do have a couple of pairs of nude wedge sandals that I like for summer dresses, skirts and shorts.
