Hi there, newbie here...
Very good site, professional and looks elegant - exactly what you would like to have for the sort of accessories you sell. Product pages are impeccable.
Your collection pages are empty - when I click the 'sunglasses' or 'aroma' etc (not Men's glasses) - there is nothing. This is okay, just make sure you deactivate these links so no one clicks through to the empty page - this frustrates people and takes them away from the site.
