An expansion can go either way. An expanding economy? Two thumbs up. But an expanding waistline rather sucks.

Put Bianca Coletti in that first category. The Puerto Rico-inspired label now includes a full line of resortwear. And like the bikinis that came before it, the snappy new collection has a tropical flair.

Solid modal tunics and rompers come in bright green, hot pink, turquoise, and black. Or go jazzier with a button-down strapless dress in a colorful pattern like feathery blue waves, purple and red tribal print, or pink and red snowflakes. The signature caftans are easy coveralls (short sleeves, V-neck, sash at the waist).

And every piece is made in limited quantities here in Miami.

We think it’s going to be bigger than ever.
