Welcome to the site Paisley

We're both on HRT for 3 months and it's a pitty you dont get the results you hoped for yet, maybe your dosage needs changing*fingers crossed*
I'm not sure what advice would fit you but I can just throw a few ideas up:
Haircut? Ask your hairdresser for a more feminine cut, bring an example. I use a wig atm but that's not something I would recommend if you can use your own hair
Makeup? Well a foundation and some concealer doesnt necesarrily have to break your boy mode but it can enhance your face looking smoother and more femme. Add some mascara and light lipgloss/stick if that doesnt make you feel uncomfy.
Clothing: Trendy unisex clothing can is pretty comforming, definately better than clear cut male clothing. I dont know if you are restricted to that however
Jewelry: A necklace, bracelet...this is one of the easier things since there's so much variation. My favourite part
I have a picture of myself on page 41. This is probably a little too much for everyday use but it's an example of how I am slowly growing to a more feminine look.
I'm sure the experts here can help you even more
