There is no shortage of products and merchandise out there inspired by Disney's Frozen, but apparently this Japanese lingerie company felt there was a void in this area that could only be filled with their Frozen bra set. Inspired by the sisterly bond exhibited in the Disney movie as well as the trend 'futago koude' (when best friends dress like twins in honor of their sister-like connection), Triumph created novelty undergarments that change color when the wearers touch one another.
The bras have a pattern with light blue snowflakes on them with a matching miniskirt. When the miniskirts are paired side by side, a heart shape forms in the same pattern. An electric circuit is formed when the wearers chest bump, which will transform the Frozen bra pattern from blue to black with white hearts.
The set consists of two bras, the larger for the 'elder sister' and the smaller for the younger. They also have heart-shaped padding.
