Hi, all!   
      
   -----Beginning of the citation-----   
   Miss Champagne was dressed in an extraordinary mermaid outfit. It was   
   green and silver with velvety sea flowers dangling from it. It had small   
   teardrop shapes of net all over it, a halter neck, a very low front, and   
   a circular gap at stomach level revealing Suky's emerald studded belly   
   button.   
   ----- The end of the citation -----   
      
   Is there a rule, or consideration why we omit an article or pronoun before   
   "stomach level"?   
      
   Bye, all!   
   Alexander Koryagin
