Help with a photo of great- great- grandma Carrick

[carricknew]

Hi everyone

I am hoping someone can help me with dating this photo (attached).
I've taken it from it's frame and there isn't anything written on the back.

I'm trying to date the photo as well as figure out how old this lady might have been when this photo was taken (I'm terrible at estimating ages).

I find her outfit rather strange- does anyone know if it's something a widow might have worn? Or maybe something religious? And what about the white part in the front?

ANY help at all would be appreciated.

Thanks in advance,

Erica

Hi Erica...I have rotated the image and increased the size for better viewing.

Thanks Brit2015
Hopefully now it'll be easier for people to look at

I'm not much good at ages either, especially as so many things can impact a persons looks, aside from their years.  Id say she is at least between 70 and 80.
