To dream of a lingerie store represents your attempt to become a more enticing, interesting, or desirable person to others. You want to be more attractive or difficult to resist. You may be trying to figure out a way to make yourself stand out or win someone over.
A lingerie store may also reflect your wish to have your ideas, beliefs, or choices become more desirable to others. You may want to make “your side” or “your plans” difficult to resist.
Alternatively, a lingerie store may reflect your wish to decide how to best sexually attract someone.
