Perhaps a little bit off-topic, but something that really irritates me about a lot of fashion advertising, as well as articles published in the "style" section of newspapers and so on, is the recent tendency to use singular, instead of plural, terms when referring to various items.
For example, "A brown shoe is now acceptable business dress and can add "pop" to your outfit".
Also, "In the above picture, Andrew is wearing a light blue pant by Zegna."
What the? Are these people only wearing part of an item of clothing? If they're wearing a shoe, then what's on their other foot?
Even further off topic, but while idly flipping through women's gossip mags in the lunchroom at work whilst toasting my sandwich, I've noticed that the same thing applies there, too, as there's quite a lot of discussion about "a dark lip really helps you to stand out" or "a strong brow is now on trend".
Aaaaagh!
