Prom week in Ukraine: Michal Chelbin’s best photograph

I went there to take pictures of kids at the end of their school years. Katya is dressed as a woman - but she's still a girl'

Two things particularly have always drawn me in my work: teenagers and costumes. I am interested in the age, around 16 and 17, that is full of transition. During those years there is confusion everywhere: confusion about roles, confusion about gender. There are a lot of changes for people to deal with.

In 2008, I travelled to Ukraine to take pictures of kids during the week of their prom that marks the end of their school years. They are very young but they are entering a stage in their lives where they are expected to act like adults. The prom is an example of this. They don't always feel comfortable in the clothes they're wearing.
