Petite vs Standard
Scarlett & Jo has an extensive range of standard fit dresses alongside a recently launched Curvy Petite collection. Petite styles are cut specifically for shorter frames — proportions are adjusted throughout the garment, not simply hemmed shorter. The exact length for each style is listed on the individual product page.
Browse our Curvy Petite collection or read the Curvy Petite Guide for more fitting advice.
