■ The catch — co-equal billing, always
It won't pass a formal invitation. The Blythe reads semi-formal and cocktail — when the invite says formal or black-tie, a midi is the wrong length no matter how good it looks. And it comes in regular sizing only.

Reads white in photos
Never wear white, ivory, cream, or champagne — and pale yellow, light silver, blush, and ice blue can read as white in flash photography. Choose deeper saturated versions or a different color family.
Sizing roulette
Lulus, Petal & Pup, and Reformation run small in the bust; ELOQUII and BHLDN size generously. Order 2 sizes when possible — formal dresses are hard to alter on short notice.
Stock evaporates
Sale-tier dresses ($60–$150) often hold ≤2 weeks of stock at a given size, and street prices swing week to week — don't wait if the wedding is under 60 days away.
Provenance — 9 sources, dated
