Here are a few of my favorite websites for Minimalist Clothing.
Zara: Most options to offer, lowest prices, and great finds for any minimalist seeker. Here is a Long Sleeve Sheer Shirt I love in nude.
Need Supply: Boutique feel website with such cool stuff to offer, variety of brands from all over any minimalist would love. Keep it simple and fresh with this Midi Peplum Dress w/ Sleeves.
Everlane: Any minimalist would love Everlane concept offering clothing from ethical factories at true cost. Looking for great minimalist staples this is the website. Chunky Wool Cardigan Coat is a perfect staple to add into your wardrobe.
COS: Is reinventing classic designs by giving them a modern take. They offer architectural designs any minimalist would appreciate. I love this Oversized V Neck Tunic fit and construction.
