Even though my personal style isn't particularly bohemian, I love incorporating 70's-inspired elements into an outfit. My advice is to pick one key piece (like a suede skirt or fringe accessory) and build your outfit around that - the idea is to keep the silhouette simple and only add a few well-chosen accessories so the end result is a nod to the era, while still appearing chic & modern.
What I'm wearing:
Cooperative tunic, Vintage skirt (similar here or here), Dune sandals (similar here; lower heel option here), ASOS clutch (similar here or here), Madewell necklaces (here & here), Sole Society ring, Lips: Revlon Smoked Peach
