How We Think About Fit

Our aim is to craft beautiful, versatile pieces that are comfortable and fit every body. However, developing products that are perfect for every body type takes time—and we are a small team. We now stock size XL in every new collection and are also hard at work developing our best selling products into sizes 2XS and 2XL. We know these are only small steps, but we have big dreams for the future.

The following models are representative for each size category, so please double check fit details on the product pages to pick the size that’s best for you. You can also chat with us or send us an email for help (fit@thisisaday.com).

Fit Guidelines

Stretchability

Our pieces are made for comfort so the majority of them contain elastane. This means each size can stretch to fit different body types because we want to create the comfiest, stretchiest and most forgiving items possible.
