I’m not sure how you feel about the states they’re in, but have you thought about Agnes Scott (GA) or Meredith (NC)? For a student competitive for the schools you’re thinking about, these would be very likely admits.
Agnes Scott is in Atlanta and is also part of the consortium that allows students to take classes at other Atlanta-area universities (like SCAD, Georgia Tech, Spelman, and Emory). From its website it says, " A Safe Place to Be You - Agnes Scott’s Safe Zone program seeks to promote both a physically and emotionally safe environment for LGBTQIA (lesbian, gay, bisexual, transgender, queer/questioning, intersex, and asexual) students, faculty and staff," (source). On a different page it says, “Despite the exclusivity that the term “women’s college” might bring to mind, women’s-centered environments of learning are typically socially progressive, welcoming and offering a safe space for various gender identities,” (emphasis added, source). @Sweetgum’s family really liked their visit there, I believe. As a NC resident, Sweetgum might also be able to speak to Meredith.
Meredith is in Raleigh, the state capital and part of the Research Triangle. Its diversity statement says,
The College admits undergraduate women students of any age, race, creed, sexual orientation, national and ethnic origin.
In alignment with our core values and our mission as a women’s college, the College respects race, ethnicity, culture, sex, gender identity, socio-economic status, sexual orientation, ability, age, national origin, immigration status, veteran status, political affiliation, religion, and spiritual identity that enrich and ennoble our campus conversations, relationships, classrooms, co-curricular programs, and work environments. Our community appreciates that identity is intersectional and that diversity extends beyond this incomplete list of categories.
The College strives to cultivate a climate of respect and dialogue around these aspects of identity. Meredith adheres to a comprehensive non-discrimination policy that recognizes differences and acknowledges that these differences are valued assets that enrich our community. [Emphasis added.]
From its statement, I can’t tell if trans women are accepted, but I think it’s worth a question to the admissions office. At Agnes Scott, I think the answer definitely seems to be a resounding yes.
When you were in Boston, did you visit Simmons? It’s part of the Colleges of the Fenway consortium where there are also cross-registration opportunities (and extracurricular opportunities) with Wentworth Institute of Technology and the Massachusetts College of Art & Design. Its notice of nondiscrimination says, “We support equal educational and employment opportunities for all persons, based on each individual’s qualifications and fitness, and we seek to administer our university policies without regard to race, color, natural or protective hairstyle, sex, sexual orientation, gender identity or expression, marital or parental status, religion, age, national or ethnic origin, socio-economic status, ancestry, disability, veterans’ status or genetic predisposition,” (emphasis added).
