See, this is the case. Ms Centenera is clearly knowledgeable of "what's in" and what's hot," she reworks the whole trendy thingy and transform it to be more of hers. I guess the dark colour and mini skirt-ankle boots combo are her favourites, and she sticks it with. Gracefully.
Hence, the lesson learned here is that, we have to figure it out. Understanding our own body shapes and what colours compliment our skin complexion will certainly add to the elegantly flavoured dressing. Me, for instance, will simply opt for a slightly A-line mini skirt or straight cut jeans to handle my pear shaped bottoms. A utility blouse like what Christine wears on the other hand, suits every body type and thus deemed the safest. But ankle boots are not for everyone though I am eyeing on asymmetrical minis.
Lastly, a closer look on her coveted outfit above. I wish I can have that skirt and pull it off.
