The Psycho Bunny Orris Board Shorts are men’s swim shorts made for beach days, pool sessions and summer holidays. They bring the brand’s distinctive style to your swimwear, with a board short design that looks sharp in the water and just as good at a seaside lunch afterwards. Choose from Black or Garden Topiary, two colours that are easy to style with a linen shirt or a plain tee, in sizes XS to XXL. Pack them for your next getaway and enjoy the sunshine with a touch of Psycho Bunny attitude.
The Orris Swim Trunk is an easy choice for summer, whether you are at the beach, by the pool or heading out on a boat day. It keeps things simple, so it works with most of what you already pack for a holiday.
It comes in a couple of colours. Throw on a linen shirt or a relaxed tee once you are out of the water, add slides and sunglasses, and you are set from morning swim to sundowners.

Sizes are waist in inches / European size. A Fish Named Fred's bermuda chart gives waist sizes only; the European sizes are paired as on its chino and jeans charts. Size 40 is not on the chart.
These are garment measurements in centimetres, taken with the item laid flat, so chest, waist and waistband are half the measurement around. Lay a similar item you own flat and compare. If you fall between two sizes, we recommend sizing up.

Your own measurements, not the garment. Use these to pick a size, then check the garment table for the style you want.
Flat tables are garment measurements taken edge to edge across the front, so they are half the measurement around. Body tables are your own measurements, taken over light clothing. Polos and tees are labelled with style numbers 2 to 9, shown under each letter size. Shown in centimetres. If you fall between two sizes, we recommend sizing up.
