You can't go wrong with a pair of Swim Shorts. They can be worn under your Es Una Rashie Dress or with your bather top, in the water, for beach walking or even bike riding.

With a wide waist band gives the ultimate comfort, flattening your middle. The leg length is just enough to cover your hips and upper thighs. Wear them over bikinis or on their own. They can be worn in and out of the water.

There is nothing more uplifting than buying something new and going down a size, especially swimwear, so we have designed our garments to be a more generous fit. Our Swim Shorts starts at an XS and go to an XXL. If you're after a firm fit, go down a size. These shorts will give a little, so going down a size is recommended. See other women wearing our range on our Size chart page.

Our models

We are showing you three models of different sizes in our Swim Shorts. Elise wears size S and she is normally a size 10 (she's the one in the sunglasses). Amelia and Erykah are both wearing the size L and they usually wear size 16. They give a little with wear so, 5% or so, if you want a firm fit, go for a smaller size.


Es Una's range is about confidence – wearing something that lifts your spirits, showcasing the parts of your body that you love. We're not about body size, we're about real women seeking a life of style without compromise. Feeling comfortable about how you look is important, but looking good for a life with no boundaries is the goal! Our designs support you to take on Summer; looking and feeling beach ready beautiful.

High tech, recycled fabric

Our fabric is 100% regenerated fibre, comprising 78% recycled nylon and 22% Xtra Life Lycra®. It has been tested by the Australian Radiation Protection and Nuclear Safety Agency, receiving an ultra violet protection factor (UPF) rating of 50+. This means it is in the 'excellent' protection category, reducing solar ultraviolet radiation (UVR) when it covers your skin. You can be confident that you're making a sun smart decision when you wear Es Una to the beach, pool or as resort wear.

One of the reasons our fabric can protect your skin is that it is a thick Lycra® to shield against sunburn and sun damage. This means that it is also less likely to cling and hug your curves in ways you'd wish it rather didn't! It's also quick drying and five times more chlorine resistant than average spandex.

Garment care

Like any swimwear garment (rashie, rash vest, rash guard, swim dress or bathers), the more careful you are with washing, the longer it will last. Your goal is to retain the fabric's original quality for as long as possible.

We recommend cold hand wash or gentle machine wash with mild detergent. Line dry out of direct sunlight. Full care instructions are on the garment label.



There's nothing more uplifting than buying something new and going down a size, especially swimwear, so we have designed our garments to be a relaxed fit for your curves. Our rashie dress range starts at XS and extends to XXL in most styles. If you're after a firm fit, go down a size or two. Remember, when you are in the water, loose fitting garments will float. This means you need to be careful of your safety in the water. Buying a more firm fitting size will reduce this.
