Formal Maternity Dresses

Maternity-Friendly by Design

The infinity dress was not built as a maternity dress, but it works as one - and works particularly well for formal events where the alternatives are limited. The elasticated waistband sits comfortably above any bump. The wrap straps tie above the bust line, leaving the bump unrestricted.

Adapts through every trimester - first trimester fits as standard, second stretches over the growing bump, third ties higher for extra coverage. The dress works for the same formal events whether you are 8 weeks or 38 weeks pregnant.

Two Fabrics, Both Maternity-Friendly

Classic matte jersey is the lightweight, breathable choice - especially comfortable through summer pregnancies and longer formal events. The soft fabric does not pull or restrict during long dinners or evening receptions.

Luxe Satin adds the polished alternative for black tie events, evening galas, and formal venues. Slightly heavier weight but the same elasticated waistband and flexible wrap design. The full circle skirt photographs beautifully across all stages of pregnancy.

Style It 99+ Ways

Two long sash straps wrap, twist, and tie into 99+ different necklines. Pregnant guests at formal events often prefer halter or one-shoulder styles - they support the bust and frame the bump beautifully without bunching at the front.

Available in Size 1 (UK 6-16) and Size 2 (UK 16-26). Watch the styling tutorials to find a flattering neckline for your current stage.

Formal Events Across Pregnancy

Galas and charity dinners: the multiway dress reads as event-appropriate without forcing into a specialised maternity formal range. Black tie events: Luxe Satin in jewel tones flatters across all trimesters. Evening weddings as a guest: deep colours and structured wraps photograph beautifully. Race days and daytime formals: lighter Classic shades work for outdoor venues.

Order Swatches First

Pregnancy can change skin tone and how colours photograph against your skin. Order fabric swatches to confirm tone in person - they ship free worldwide.

Most pregnant guests order swatches early in the formal event planning process, with enough time to settle on a colour and fabric before the dress is needed. The infinity design forgives last-minute fit changes - the elasticated waistband adapts to whatever stage you are at by the event date.
