Personally, Ive never been a great fan of the whole retro collage design style. It just didnt seem that impactful when compared to really strong elegant visuals. With that being said though, this approach does seem to work perfectly for this particular brand.
Also, underneath all the visual noise seems to be a really well executed site. I especially liked the Shop page with perfectly timed animations and with just the right amount of Easing & Speed.
The only thing Id do differently would be to build on the theme and create an equally crazy Lookbook page. But other than that, Kudos on a job well done.
