I actually got interested and looked up aesthetics - did you know that there is literally a Coastal Grandmother aesthetic??

Anyway, I still haven't found an existing one that actually matches what I think of as my aesthetic... I'd say I kind of go for glamorous stuff (which means my own idea of glam, not necessarily what's generally thought of as glamorous) mixed with more real genuine things?? I often don't like the actual trends out there.

Anyway, I tend to like bright colors and elegant-but-girly things? I don't think elegant is quite the right word - I don't like to be too formal, but I don't like stuff that's just plain or baggy or sloppy. So for instance, I really like to wear skinny jeans (either light blue or medium, bright blue, not navy or dull blue) and ankle boots and some sort of pretty t-shirt, with a few accessories like a bracelet to add something extra. 

In general I guess my aesthetic is (following Silver Crystal's example here :D) sunsets, sea-green and peach color combos, garnets, the excited hush of wonder that falls over a room when everyone realizes it's raining, golden sunlight in the evenings, family evenings round a fire, evening dresses, Japanese maple leaves glowing against a blue sky, Carlos Baute songs, dewdrops on the grass, the list goes on :)
