Is that a screenshot from the actual show? It's been so long since I watched Pony Life...I really am going to have to rewatch the whole thing sometime I meant to do so in the past but didn't feel like it, but maybe this time I'll bother to do it.
I mostly prefer the new ones - with the exception of Sunset. The newer clothes are good but I prefer the older look. There's just something about all the other newer ones that I find appealing.
