what to wear to a beach that has cold weather?

That sounds good

Have a couple of tank tops

long sleeve shirts

short sleeve ts

a light sweater to wear over tanktop

and the swimsuit

mix and match

You sound ready

I would skip the jeans and go with long wrap skirts. You get coverage against the cold but don't lose the beach feel of your look. I use a shawl as a cover up with your tank tops for the same reason. If you're wearing sweaters and jeans you might have well as gone camping in the mountains. ^_^

Sweatshirt and jeans. Maybe a jacket. Dress like it's going to be fall. I would do long sleeves and maybe layers to a degree that way if it warms up then you can remove a layer.

pants, shirts with sleeves, jacket, comfortable shoes, socks, etc.

I wouldnt wear jeans

I would wear shorts

and a short sleeve shirt

Bring a sweatshirt too

i would wear jeans(if it gets hot u can role them up), a long/middle sleeved shirt with a cute sweater(u can take it off if it gets hot) and then a bathing suit incase u wanna go swimmin

east coast or west coast? west coast wear jeans, a hoodie, scarf and beanie & tennis/skate shoes east coast wear jeans/slacks, wool coat (pea coat if you can) or sweater, scarf, hat & boots or sturdy shoes.

long sleeved shirts and pants i guess
