The trick to wearing extremely dark nail colors is to keep your nails short and nicely shaped - aim for a sort of squarish oval shape.
Check out what the stars are using on their tips:
Amanda Bynes rocks a dark, metallic, purple shade. For a similar look, check out Sally Hansen Diamond Strength nail polish in Vixen.
For a trendy look, copy Eva Mendes and choose a dark navy shade. Try OPI nail polish in Russian Navy.
Sarah Michelle Geller also chose a deep blue shade for her tips - this shade is so dark it is almost black. Shades to try: OPI nail polish in Light My Sapphire and Sally Hansen lacquer in Navy Venom.
Want nails that are vampy and chic? Then Jessica Simpson's dark maroon shade is for you. Try OPI nail polish in Lincoln Park After Dark.
And for a tried and true classic look, red nails like Gwen Stefani's are the go-to choice. Check out OPI polish in I'm Not Really A Waitress.
