x REVOLVE Gemma Midi Dress

This midi dress is cut from a lightweight, wide-ribbed knit that hugs the frame without constricting. The deep V-neckline and high side slits break up the linear geometry, while the slightly flared, slit cuffs add a subtle, liquid movement to the sleeves. It trades Costello’s usual red-carpet theatricality for a stark, minimalist tension that relies entirely on the precision of the ribbing.

Safety Rating: Fair

Analysis: The composition is a blend of 95% cotton and 5% spandex. While the high percentage of natural fiber offers good breathability, the inclusion of synthetic elastane for stretch places this in the fair category for material neutrality.
