We obsess over fit. With every piece we make, we do multiple rounds of fittings on the same fit model to ensure that the fit is perfect and consistent across styles. Sizes 00-14 are fit to a size 6 and sizes 14W-20W are fit to a size 16W.

We recommend buying true to your size using the below size chart as a guide. However, some styles are purposefully cut differently to accommodate a range of body shapes and sizes. To make selecting a size easier, we’ve included detailed fit notes and individual size chart on each of our product pages.

If you have any questions about fit or need help selecting your size, please don’t hesitate to call us at (212) 979-2229 or email us at info@ofmercer.com.

How do your straight and plus sizes differ?

For sizes 00 - 14 we fit on a size 6 fit model and grade the pattern proportionally smaller and larger. However, a size 6 can only be scaled so much without becoming disproportionate. As demand for more sizes grew we knew we needed to create new patterns so as not to lose the fit integrity that we, and our customers, value.

For sizes 14W - 20W we fit on a size 16W fit model. In addition to hiring a dedicated fit model, we adjusted seams, proportions, and hemlines to offer the same superior fit and contemporary style of our existing collection, tailored to sizes 14W-20W.
