Would this outfit be ok for myself to wear for an upcoming FALL photoshoot?

I’m not sure if that’s too “wintery” or not? Ive attached a photo of it. I would pair it with black over the knee boots and possibly a black hat similar to the other photo posted (basically how my outfit would look except the dress would be brown and I would be pregnant lol). It’s fairly long, but I am currently pregnant so I would have to make sure it’s not too short (although I don’t believe it would be as I’m very short myself lol) It’s for a family fall photoshoot coming up.

Thoughts? It’s just myself, my husband and my 2 year old son. My husband is wearing black jeans, grey timberland boots, a brown hoodie (similar to the same colour as my dress) and a light blue jean jacket with some brown corduroy on the collar). I’m still completely unsure about what my son should wear thought so if you have any ideas that would help!
