Elegant Collection [Northary]

Treat yourself to some special lingerie as a reward for a year of hard work. For Christmas gift exchanges, this gorgeous camisole is sure to be a hit. Welcoming the New Year in new lingerie makes you feel like you’ve hit the reset button!

—A Beautiful Silhouette the Moment You Put It On—

Thanks to the unique side-gathering effect of the Elegant Collection bras, it gathers your bust and focuses it on your décolletage, creating a sleek, streamlined look along your sides and back!

It provides firm support without feeling constricting.

The moment you put it on, it creates a beautifully shaped bust and keeps your breasts looking their best for hours.

1. The Power Lift Panel, reinforced with a double-layered structure, lifts and gathers the bust from the sides.

2. Stitching along the sides of the cups holds in side bulges for a sleek underarm look and a refined silhouette.

3. The shallow front center design, combined with a 1- or 2-step process to gather the bust, creates a deep cleavage and a full, rounded décolletage.

Choose from 4 styles of panties!

Price range: Bras 3,960–5,390 yen, panties 2,200–3,080 yen, camisoles 7,590 yen, garters 5,390 yen (prices include tax).
