Is the girl holding the flag even on the team? She’s not wearing the uniform. This competition is a meritocracy. Go USA.
I think she’s probably part of the Romanian staff. Kind of like the people who hold the signs with the country name in the Olympic opening ceremonies.
The caption quoted in this thread is a little confusing. I'd assume that the seven people named in it are the seven people who aren't in a bear costume, but I looked for the two who don't have names that are traditionally masculine in English. If these search results aren't misleading, these two are male too. I also checked against a small number of other team pictures online.
So my guess now is that these uncostumed people are the six students on the team with someone like a staff member assigned to hold the sign (see post #28), and the team coach named in the caption is not in this picture.
I can imagine a different uniform color and style for girls, though such a practice may be condemned as SEXIST and NON-INCLUSIVE (of those competitors who identify as "genderless," a member of some fifth gender, or as a complex mix of genders that shifts according to the weather and the phases of the moon).
