Hi! I'm working on feminizing my appearance too! Tops are really hard, and you said you've already got girl jeans, so I've got nothing to tell you there. Cardigans are in, even for boys, and it's fall/winter so you can do scarves too. I'm a huuuuge fan of long tshirts and long hoodies. They kinda give the impression of wearing a dress, without being a dress. You can even put a boycut tshirt on top of a long tshirt in contrasting colors, and it ends up looking quite femme.
