Meet the softer, thinner, lighter counterpart to the traditionally heavy Oxford. Our Summer Oxfords feature the same, slightly nubby texture but in a much finer weave. Supremely casual, these easy-to-wear, no-pressing-required shirts come with a slight color boost—we named her Bay Blue because of the deep, oceanic shade. Pair with light neutrals to balance out the bright, or go full-on with contrasting colors for a head-to-toe pop.

Fantastic thinner summer version of the oxford, colour has remained vibrant.

Jason S. (Berwick, VIC)

These summer-weight oxfords are great. They wear just like your favorite OCBD, but a bit lighter, making them perfect for warmer days or layering. And the saturated pop of color keeps things fun.

Jeremy M. (Highlands Ranch, CO)

Of all the ratio shirts I have purchased the two Summer Oxfords have been my least favorite. Fabric is nice to the touch but the shirts are almost metallic in appearance. The color almost "shimmers". Blue is less metallic than the berry (pink) but both have a similar look. They definitely do not look the same in real life as they look online. Also, both seem to wrinkle more quickly than the other Ratio shirts I own. I still wear them but they are not heavy in the rotation.

Fabric is a good weight, a great color, and has a nice sheen to it.
