Learn how to select between the SIN and SONGE push-up bras from Maison Lejaby. This guide covers key differences, fit tips, and decision rules for a natural, comfortable lift.
Quick answer
Choose the SIN for a nearly invisible push-up under fitted tops, or the SONGE for a decorated yet comfortable lift with recycled French lace.
Key differences between SIN and SONGE
The SIN push-up bra focuses on invisibility with opaque mesh cups and embroidered sides that stay hidden under clothing. Its progressive foam creates a natural, subtle lift. The SONGE bra, on the other hand, features molded cups covered in French floral lace, offering a decorative look that still feels smooth under many outfits. Both bras use recycled materials in their lace or mesh, but the SONGE's lace is more visible and ornate.
The main trade-off is between discretion and decoration. If you prioritize a seamless look under thin or light-colored tops, the SIN is the better choice. If you want a bra that adds a romantic, lacy detail even when partially visible, the SONGE delivers that without sacrificing comfort or lift.
Decision rules: SIN vs SONGE
- Choose SIN if:: You want a push-up bra that remains invisible under tight, thin, or light-colored clothing. The opaque mesh cups and embroidered sides are designed to not show through.
- Choose SONGE if:: You prefer a push-up bra with visible decorative lace that adds a romantic touch. The molded lace cups provide a natural shape while the floral design stands out.
- Consider fit preferences:: Both bras offer a natural, comfortable lift. The SIN uses progressive foam for a subtle boost, while the SONGE's molded cups create a smooth, rounded silhouette. Try both if you are unsure about the level of padding. Check the size chart and consider your typical outfit necklines before deciding.
