London girls seem super into Mulberry, and every second one seems to have a Le Pliage. Burberry trenches are very popular, but not so much the handbags, especially the nova check because the pattern has been "ghetto-ised" over the last decade or so. Here in London City (the business district) the designs I mostly see are:
1. Longchamp Le Pliage
2. Mulberry Bayswater
3. Mulberry Alexa
4. Michael Kors Hamilton
5. LV Speedy - mono or damier
6. LV Neverfull - mono or damier
7. Mulberry Daria
8. Hermes Birkin
9.
Prada tote - the structured kind, in Saffiano leather
10. LV Alma - mono or epi
Pretty sure at least 90% of the Birkins and 50% of the LVs are fake, but mostly they seem like decent enough replicas that I can't tell for sure when just passing on the street.
Oh, and like millions of Alma-shaped patent bags that I think might be Paul's Boutique? And quite a lot of Ted Baker bags too. I don't really think of them as "designer" though.
