No. I think that people look tacky when they do not dress age or body appropriate. This goes for everyone, men, women, and the gender non-conforming.
A middle aged man looks ridiculous walking around dressed like his 16 year old son, just as the middle aged mom looks, when she tries to dress like her daughter, even if it is a hot clubwear dress. She may have the body for it, but not the face.
Speaking strictly of CDers though, when they dress way younger or with shorter dresses, or body hugging clothes for their ages (or body types), they are noticed and stared at even more, just as are the GGs who do the same thing ... and not for good reasons.
