When the teens take the formula that transforms them into giants, they outgrow their clothes and are temporarily nude. Private areas are strategically hidden behind hands, furniture, etc.
When the teen giants make their own clothing, it does not cover much. The boys wear homemade togas, while the girls wear the equivalent of bikinis.
Several girls at an outdoor picnic wear bikinis for no readily apparent reason (not at a beach, lake, etc.).
Lots of lingering shots of females' chests, hips, and backsides as they dance in various scenes.
A normal-sized male is picked up by a female giant and placed up against her chest area.
A teen girl tries to get information from a teen boy by kissing him repeatedly and then asking if he is ready to tell what he knows.
