Venus symbolizes love, beauty, and money/earned income. It reflects how you relate to others and your environment, and also how you see yourself through another’s eyes.
When Venus moves into Pisces (the unseen realms of life; the divine) we see the world in full color. There is so much more to this vast, mysterious universe than the meets the eye. This transit can inspire you to connect with something bigger than yourself and your everyday routine (Virgo, the opposite sign of Pisces rules the day-to-day stuff). You may do this through a walk in nature, spending time with an animal friend, meditation, yoga, listening to or creating music, creating art, going on an adventure – whatever it is that inspires you). 
Like the “App,” Snapchat, Venus in Pisces can adorn you with a pair of cool-looking, rose-colored glasses – keep in mind, especially if you have met someone new, that sometimes things appear “rosier” than they actually are. You want to see the beauty in everyone and everything thing now, and it’s easy to overlook details. (Pisces is not, ahem, known for their detail work – anyone who is friends with or married to a Pisces will probably laugh, knowingly, at this).
You may feel more compassionate now and able to forgive more easily; this is a “live and let live” transit. Speaking of living, I once shared an apartment with a friend who had and abundance of Virgo and Aries in her natal chart; she had many positive qualities (e.g., proactive, energetic, reliable and disciplined to name a few) and she was also hyper in tune to details (at the expense of the bigger picture), and quick to criticize others – she seemed to see the world in black and white. I often found myself saying, during that year, the phrase “Live and let live.” Pisces is like a soothing balm in that way; it’s a non-judgmental and open-minded, and it’s shadow side is that it is susceptible to slipping into the role of the victim, which is often more subtle than we realize. Pisces is like a sponge, super sensitive, absorbing everything, including pain and negativity, and so people with Pisces prominent in their charts need to learn to create firmer boundaries in order to protect themselves. Pisces is also the chameleon of the zodiac; they can become what they think you want them to be (many talented actors have this sign prominent; they are able to step into someone else’s shoes, so to speak).
These are all themes to be aware of when Venus enters Pisces. Are you honoring yourself and your needs in relationships, or are you giving your power away? There is a soft and, often, foggy quality to Pisces and boundaries can play tricks on you now, or people you love and are in relationships with can seem out of reach. Relationships with composite Pisces or 12th house energy strong are often hidden relationships; they can also be beautiful and soulful.
You can use this Pisces in Venus Transit to connect with others in a deep and meaningful way, to enjoy romance and beauty, to forgive past hurts and see situations from a wider perspective, and to create (e.g., art, poetry, music) from your heart — basically, to realign with what really matters to you.
