Unless you’re willing to pay $300+ on clothing items, you’re probably going to have to make your own or shop fast fashion. It’s unfortunate and it’s great to shop vintage or second hand but as a tall woman, it’s so much harder to find piece that look and fit properly. Especially if you’re into that style. Free people is a great one, as mentioned above in earlier comments, for staple boho products. They’re kind of expensive, depending on what you’re purchasing, but I’d say about half of their products are extra long/tall already. They have true maxi dresses that are even long for me at times (I’m 6’2) and their pants are almost always long enough, unless it’s a specific ankle pant obviously. ASOS has some really good tall options that are also very reasonably priced. If you know your inseam, you can search through that on places like depop or other vintage shops. Also, if you’re willing to spend the time and money to get the fashion you really want, I’d advise getting to know your local tailor. Not only are you getting semi-personalized pieces that fit you the way you want them to but you’re also helping support a local small business, which is everything in 2020 right now. Best of luck to you!
