The focus of The British Guide to Showing Off is the Alternative Miss World Show, a magnificent costume-pageant and performance-art event that has been taking place since 1972. The eccentric and egalitarian competition, inspired by the Miss World contest, was devised to celebrate diversity, imagination, creativity, and very much the ethos of 'anything goes'. With characters, themes, and costumes that appear to have sprung from the deepest corners of the creative universe, the spectacle is a feast of color, humor, subversion, and an all-embracing collective spirit.

Through the coverage of the 2009 show, the movie offers up-close and personal encounters with a myriad of fascinating characters including participants, past winners, audience members, and Logan himself.

The heart of the documentary is a deep dive into the life and world of Andrew Logan. Revolving around his eclectic artistry, it reflects his world view that regards life itself as a work of art.

We see him as he sculpts, creates the show, and interacts with a broad range of personalities from various walks of life. Much focus is given to his astounding process, focusing on the elaborate, inclusive, and celebratory heart of the event rather than its competitive aspect.

At the surface, the film might seem like a continuous procession of fabulous costumes, eccentric personalities, glitz, and glamour.

This underlying message resonates throughout, with Benstock ensuring that the human have their moments amid the spectacle.

Furthermore, Brian Eno and Grayson Perry add richness to the narrative. They participate in the show and offer their insights about Logan's creation, thereby enlightening viewers about the grandeur, significance, and immersive artistry of the event.

Its pulsating rhythms and expansive panoramas beautifully support the visual narratives, adding another layer to the mischievous spectacle.

Filmed over a span of five years, the documentary also circles back time and again to the history of the event.
