The Crab-like supernova remnant 3C 58 was observed with the VLA at frequencies of 1446 and 4886 MHz, with resolutions of 2.0 and 2.45 arcsec, respectively. It is found that 3C 58 has a considerably larger extent than previously realized, particularly at the eastern and western edges and above and below the central bulge. Some parts of the periphery are markedly confined while others are not; some confined-edge regions are slightly limb brightened. The fainter outer envelope contains extensive filamentation as do the brighter central regions. The filament profiles are nearly identical at 1446 and 4886 MHz.
