Clearance sale update

Due to high demand, several styles are now close to selling out. Once a size or colour is gone, it may not return at the current sale price.

The one-piece that makes every summer moment easy.

A square neckline and slim spaghetti straps give this one-piece a clean, flattering silhouette, while the stretch fabric holds its shape through swims, sun lounging and everything in between. It's simple, streamlined and built to last.

Wear it poolside, on the beach or layered under a sarong for brunch after your swim. However you style it, this piece is designed to make you feel confident and comfortable all season long.

Wasn't expecting much for the price honestly but the quality is so well done. Runs true to size for me.

Got this for my mum's birthday and she wore it the same day. Feels way more expensive than what she paid.

Already own two other pieces from this store and this one might be my favorite. Solid stitching, no loose threads.

At The Bay House, we’ve always believed that getting dressed should be one of the easiest parts of your day. No overthinking. No choosing between looking beautiful and feeling comfortable. Just pieces you can put on, feel good in, and get on with whatever the day brings.

That’s why we choose every piece with real women and real life in mind. Flattering shapes, effortless comfort and styles that feel special without feeling like you’re trying too hard.

Because when something truly feels like you, you don’t just wear it once. You reach for it again and again.
