I bought one at rebel sports (I think? One of those big chains anyway) late last year. The sales lady recommended I get a netball skort, which I did (literally netball - it has he netball Australia logo on the front). I loved the idea of the practicality of the tights + vanity of the overskirt and the skort she recommended was only about $30. "All the runners love these". Ha!
Tbh - I hate it. The tights ride up and I find it very uncomfortable. No way could I do any decent distance in it. I am not sure if its just the particular one I bought, or even the sizing, but it did feel right in the store - it's once I get running I have problems. Very disappointing. If I didn't live 5 hours away from the store, id return it.
So, there's a recommendation for what NOT to do
hopefully someone can give you some more positive advice and I can try something else too
