Fit Tips
Numi Essential Undershirts: Our undershirts are tightly fitted to the body, with some stretch to the fabric. If you fall between sizes on the chart, we recommend choosing the larger size as they are a snug fit.
Numi Sustainable Silk™: Our silks fit true to size. If you fall between two sizes on the chart, we recommend choosing the larger size for comfortability.
