How to fix black lines on arms on ''Alex'' style skins in 1.7?

[KevinsToys]

So this one Alex style skin I have has black lines on the arms when I'm on 1.7, does anyone know how to fix this?

When changing your minecraft skin, instead of making the skin "Classical" make it "Slim".

I have it on slim, but it seems like slim doesn't work on 1.7
