I wonder if really tall women have a harder time with clothing than even really tall men have. My sister in law (wife of H’s brother) is about 6’3" but I just have never asked her about how she gets her clothing. She always looks nice so she obviously has made things work for her. Probably the type of thing that if I were similarly tall to her, I may have been more inclined to get into the nitty gritty with her about being that tall as a woman. But since I’m average height , I just don’t get into it. One of my kids dropped by last month with some friends. One was a young woman,a very bright computer scientist , very attractive , confident, and quite tall (definitely over 6’). She was striking. I was tempted to ask her how tall she actually is but bit my tongue. She probably gets asked that enough already!
My husband has had good success with L.L. Bean . He gets a lot of his clothes from them as they have tall men sizes. I don’t think they have similar tall sizes for women though
