1. Thou shalt not peacock
Think David Gandy: less plumage, more refined tweaks to show off your personal style.
2. Thou shalt not photobomb
Don't run around actively trying to crash other people's pictures. Let's face it, you're a snappy dresser - you'll probably end up on a street style blog without even trying (much cooler).
3. Thou shalt not cross thy legs in the front row
You will get shouted at by the chaps in the photo pit.
4. Thou shalt remember to eat
It’s all too easy to get swept up in the day. Remember: sustenance is essential (here's some seriously stylish places to re-fuel in the capital).
5. Thou shalt not recycle opinions
Be original, because you’ll definitely be caught out otherwise.
6. Thou shalt clap
Of course take a solid finale shot for your IG, but then put your iPhone down and make some noise for the designers - they've all worked damn hard.
7. Thou shalt not take blurry catwalk photos
If even a maximum slide of Instagram's sharpen tool won't save a shot, ditch it.
8. Thou shalt bring a battery pack and charger cable
It's quite simply the easiest way to make friends at fashion week. You never know who will need your help in an iPhone emergency...
(P.S. after much on-the-job product testing, we recommend Mophie's clip-on cases.)
9. Though shalt not covet the style of others
You do you, man.
10. Thou shalt not take the name of GQ in vain.
Obviously.
