I'd say going by her checking her purse, I think the joke they're going for is as HoshinoK says.

Because her outfit is already a bikini.

Also where is Diona?

A little bit of column A, a little bit of column B. Mona's poor, so she can't afford a "real" swimsuit for the occasion, but the outfit she wears already is perfectly suited for the water. Being a hydromancer and all that.

I think Mona also can't afford any drinks.
