unassuming

That evening found Selwood, quietly and unassumingly attired, examining the purlieus of Soho.

These virtues he wore modestly and unassumingly as an accustomed garment.

Unless you sat across the tea-table from him and now and then, while he quietly and unassumingly talked, met his eyes.

He unassumingly disposed himself for a stay, examined the backs of several books, and acted altogether as if he were at home.
