The ubiquitous blue and white porcelain is the first non-trendy trend that comes to mind. It really works in so many decorating styles and has been around (in the West) for hundreds of years. It was never really out.
Equestrian themed fashion is easier to find lately but the hunt country interior has really never left.

The traditional and masculine style is one of my favorite.
The third trend that isn't, is Chinoiserie. It may seem redundant but the blue and white porcelain is sometimes just blue and white without a Chinois theme. We certainly see a lot of this stylized Eastern look but it is a historically significant style that has never been gauche.
