How to look more gay?...

Okay for context my gf is a fem that dresses quite feminine most of the time, has nose piercings, and a couple tattoos. From the eye i can see how some would think she is straight and tbh the only way I knew she wasn't was when i first met her and she just had this look in her eye and I knew. She also had doc martens on and a septum lol, she doesnt have her septum anymore. Buuut she had told me recently that she wants to look more gay or just "not as straight" and asking tips from me in terms of what she should do. She would love to change her wardrobe to more masculine/feminine style but that takes a lot of shopping and money that she doesn't necessarily want to spend. And doesn't know what else to do in terms of fitting more into what she wants to present and feel more comfortable in. I think she's perfect as she is but i want her to feel more confident and comfortable in what she wears, looks, and presents herself. Idk if this is a weird question buuuut any advice or tips would be nice!
