comment Constructing vector bundles of specific stiefel whitney classes?
Problem $8$-$B$ from Milnor & Stasheff provides a restriction. Namely, if $w(\xi) \neq 1$, then the smallest $i$ such that $w_i(\xi) \neq 0$ is a power of $2$.

comment Integrability at $z$ of the 2-form $ d\omega=\frac{\partial_{\bar{\zeta}}g(\zeta)}{\zeta-z}d\zeta\wedge d\bar{\zeta} $
"At MSE no one could help me, I hope to be more lucky here." You posted here only an hour after posting on MSE. You should be a little bit more patient.
