The Sunday Silk Slip Dress (Adjustable Straps and Built In Bra Cups)

The built-in bra — what it actually does

The interior bra is a structured fabric layer sewn into the dress itself. It provides coverage and security — not push-up, not lift, not cleavage. No boning, no underwire, no elastic digging in. The padding is removable so you can customize how much structure you want.

Ideal for A–C cups worn braless. You can dance, sweat, travel, and move without anything slipping or shifting. For D+ cups who want additional lift for a formal occasion, a plunge bra can be layered underneath — but most women find they don't need one.

Key features

• Built-in bra with removable padding — full coverage, no underwire, no shift
• Adjustable multiway straps — wear traditional, crossed, or halter; fits every torso length
• Bias-cut midi length — skims and drapes without clinging; universally flattering
• Dual side slits — ease of movement without sacrificing elegance
• OEKO-TEX certified — chemical-free dyes, non-toxic processing, safe for sensitive skin
• Machine washable — use the included mesh bag on a gentle cycle

Material

100% Mulberry Silk · 19 momme · 5A grade · OEKO-TEX Standard 100 certified · Chemical-free dyes · 100% biodegradable

19-momme is a meaningful benchmark — heavier, denser, and more durable than the 6–12 momme silk used in most slip dresses. The 5A grade is the highest classification in silk production. This is the real thing.
