It can reach {{convert|30|cm|in|abbr=on}} in total length.{{FishBase |genus= Iniistius|species= trivittatus| month = October | year = 2013}}

It is deep bodied and extremely laterally compressed as in all members of its genus. It is distinctively coloured, generally pale yellow with three broad, dark, vertical bars on its body. A further diagnostic trait is the presence of a deep notch between the first two spines of the dorsal fin.
