La Sirene designs swimwear as coordinated sets rather than separates — one-pieces, bikinis and cover-ups built around the same silhouette family, so a top, a bandeau and a matching skirt read as one outfit rather than three pieces that happen to share a print.
Swim
The range splits between structured one-pieces — Milan, Lara and Anna — and bikinis sold as grouped sets, including bandeau styles. Most shapes appear in both formats, so the same cut can be had as a one-piece or a two-piece.
Dresses and coordinating pieces
Several swim styles have a matching dress or skirt designed alongside them — the Anna Bandeau and Anna Skirt pairing, for instance. See matching sets to buy the pieces together.
Sizing
Where a bikini is sold as a grouped set, top and bottom can usually be sized independently. Check the individual product page for fit notes before ordering.
