It can sometimes be difficult to distinguish between colors, on Buffy the Vampire Slayer. This is mostly due to the lighting. In season 7 episodes "Never Leave Me" and "Bring on the Night", Sarah Michelle Gellar can be seen wearing a Nanette Lepore crochet top. Because the color is somewhat indistinguishable, there has been some debate on whether the blouse is brown or black.
When sold in stores, the blouse came in both black and brown. From the screencaps it can be a bit difficult to precisely identify the color, she is wearing, but I believe the top is brown and here is why. The color of the blouse is more apparent when Sarah Michelle Gellar is in the well lit bedroom. And there you have it. Mystery solved. Case Closed.
Now, that isn't to say that SMG has never worn this top in black, because she has, just not on screen. As you can see, Sarah Michelle Gellar wore the top in black at the UPN Upfront party in May of 2002.
Whether it's a brown or a black top, I think we can all agree that both look beautiful on Sarah Michelle Gellar.
