Translation:I do not have a scarf and I do not have a skirt.
hmm i would accept that somehow.
In fact I would add لا as in: ليس عندي وشاح ولا تنورة (this is equivalent to saying: I have NEITHER a scarf NOR a skirt.
Worth noting, when I first read your sentence, I got the impression that the scarf and the skirt are like one set of items, like they do come together. So, probably for more clarification (or rather a delicate one) it would be better to use the negative twice. Other than that, your sentence is OK I guess.
