I'd say don't. As a Saggitarius, the description here of the zodiac is laughably ill-fitting to me, and I can see at least four other signs that sound better-fitting.
Besides, if we're going by arbitrarly-drawn clusters of stars (clustered differently in different cultures) determining the fate of all humanity, there are 13 constellations in the zodiac, but they lowered it down to 12 because the 13th was in line with the sun for a shorter period of time, and 13 wasn't a lucky number.
So just enjoy the themed underwear.
Pisces Bra
Two Fish Tied with a RibbonFish-Tail Necktie Ribbon BraFin Ribbon and Foam PantiesIn fortune-telling, Pisces are true romantics. It is rare for them to express violent or harmful emotions outwardly, but do no think for a second that they aren't capable of carrying intense negative emotions just below the surface. They have a strong sense of self sacrifice and a strong heart, and are more than willing to put people around them before themselves.
