Bianca Censori will look picture-perfect for her hubby Kanye West for Valentine’s Day — ’cause she was out getting a spa touch-up the day before!

Check it out — a photog caught her headed out of a Los Angeles medspa Friday looking as radiant as ever … and showing off what her mama gave her in one of her signature curve-hugging outfits.

The architectural designer dolled up in a pair of lavender tights that left little to the imagination and an off-the-shoulder chocolate brown blouse … finishing the body-contouring look with a pair of white heels.

Bianca stepped out solo a few weeks back as well when she headed to a facial clinic in West Hollywood … and she opted for another skin-tight look.
