Here are a few things that give off so damn much lesbian vibe ;)

Short hair

Masculine style

Rings or jewelry

Feminism ♀✊🏽

Hold Cups and Glasses that way:

With ring and middle finger through the hole

From above

Dyed Hair

Liking horoscopes and stars

Cuffed Jeans

Undercut

Beanies

Paying Attention to the environment (global warming and pollution)

Chucks

Girl in Red (and other artists)

Short nails (obviously...)

Frogs

Red (Color)

Plants

Vintage paintings

Drive-in-theater

Records

Belt chains

Eyebrow slits

Bucket hats

Homemade earrings

Crystals

Tattoos

This is just my opinion and it doesn't have to mean that these things are immediately lesbian/queer ;)

Love y'all <3
