Cassandra oh yeah I'd find her very attractive myself. I'd classify Cass as being a soft butch myself not too masculine and just the right amount of feminine to balance it out. She's the strong warrior type, a leader, has a low tolerance for BS, she's quiet fiery, she's tough. I admire her pragmatic attitude and the moments we saw her let her guard down to reveal her softer side i.e her admiration/crush towards Hawke dueling the Arishok to save Isabela, are very endearing. 
Her look also, the femme look is fine and all I do like it but it's not my preferred type personally. I appreciate the androgynous look in women more which is the style I rock in RL coincidentally.
Also short hair ftw, not just because I have it too, I'm not doing much to banish the stereotype for my sapphic sisters right now, oh well. 
Where as I enjoy dressing up, my long hair, wearing dresses and skirts, and being silly and playful, and when seeking a female partner I like someone very similar to myself, I just think it's more fun that way. Probably why she isn't really my type. To much time getting her to relax and let her hair down. I don't mind a strong woman really, as long as I also find her fun.
I also like long hair, is fun to play with and gives me more handsy things to with my partner that's intimate without being overtly sexual. I miss that with short haired women. Though I can live with shorter hair, ultimately it's who the girl is over any of that.
But I'd be a liar if I didn't say I like a girl with a feminine figure. Call me conditioned by society, but it's visually what I like looking at most. Is more aesthetically pleasing for me. I feel kind of bad about that sometimes because I don't have that figure myself and that judgement no matter how small is there, but it's never stopped me from being with someone I cared about who didn't fit my ideals of physical attraction... long run on, not sure if sensical sentence that that was...
