Sephora Joins The Matte Trend With The New OPI Matte Nail Colour Collection. Unless you've been living under a rock, you already know that matte nails are the hottest thing around these days and Sephora is jumping on the trend with the new OPI Matte collection. I'll admit that I am a bit of a matte girl so this collection will be one in which I will be trying. The collection will feature three shades of the most popular OPI for Sephora nail colors Domestic Goddess, Metro Chic, and Where’s a Tire Jack? Like many of the original OPI For Sephora nail colors the bottles are priced at just $ 9 each and are available at Sephora.com and Sephora Stores.
