zentai
skintight garments that cover the entire body
uncountable
Saturday morning Tori was due over so we could go shopping. I thought I'd surprise her... so I set up the TENS unit, then locked on a zentai suit over it, then put a corset on over that, and locked a belt over that! Finally I chained myself to the bed so I couldn't do anything about it.
Where it comes from
From Japanese ゼンタイ, a portmanteau of 全身タイツ (zenshin taitsu, “full-body tights”).
