We present the detailed optical evolution of a type Ib SN 2015dj in NGC 7371,using data spanning up to $\sim$ 170 days after discovery. SN 2015dj sharessimilarity in light curve shape with SN 2007gr and peaks at M$_{V}$ =$-17.37\pm$0.02 mag. Analytical modelling of the quasi bolometric light curveyields 0.06$\pm$0.01 M$_{\odot}$ of $^{56}$Ni, ejecta mass $M_{\rm ej} =1.4^{+1.3}_{-0.5}$ \msol\, and kinetic energy $E_{\rm k} = 0.7^{+0.6}_{-0.3}\times 10^{51}$ erg. The spectral features show a fast evolution and resemblethose of spherically symmetric ejecta. The analysis of nebular phase spectrallines indicate a progenitor mass between 13-20 M$_{\odot}$ suggesting a binaryscenario.
