Maillot de bain pain de sucre

A delightful combination!

"Maillot de bain" is French for "swimsuit" or "bathing suit", and "pain de sucre" is French for "sugar loaf" or "sugar cube".

So, "maillot de bain pain de sucre" is a playful and whimsical phrase that might be used to describe a swimsuit with a sweet and sugary theme, perhaps with a design that resembles a sugar cube or a loaf of sugar. It could also be used to describe a swimsuit that is as sweet and delightful as a sugar cube!

In any case, I hope this helps, and I'm happy to have been a part of your linguistic adventure!
