Here at Palmer Preston we aim for a comfort fit vs a fitted cut most of the time. That said our size guides are typically based on wearing as a comfort fit. Not restricting, hugging, or tugging. Very few styles are what we call "true to size" aka along the body, draping the midsection, fitted on bust. Each individual product has its own unique size listed in the item specific product description. In general here is a blanket guide (idea) for when navigating Palmer Preston apparel offerings. In addition to knowing your numeric size it is important to know your body shape and garment styles you like or dislike on your personal shape. This will ensure the best fit, the first time, and each subsequent time when ordering anywhere online.
