Nope, she isn't listed on any passenger lists.
It's possible that she might have travelled as a crew member and so not been listed outward bound as a passenger.
Nor did she die in England under her maiden name.
I suspect that she got married, and there are four possible marriages.
Two of those are in the north of england and are likely to be two local women who were born in a similar time frame.
I suspect that she either married in Lambeth or in Surrey in 1915.
Doubtless you know that she was a dressmaker in 1911, so that, and her age and her father's details on the marriage cert should prove or disprove the marriage scenario.
She was born in 1886.

The 1911 census lists a single bank clark called Rupert Edward Sutton born 1886 in Oundle Northamptonshire and living as a lodger in 37 Semilong Road, Northampton in 1911 but I can't find a birth record for him.
The 1901 census says that his father was a 53 year old retired school master called Francis William Sutton who was born in Beccles, Suffolk in 1858.
53 seems a bit young to have been retired back then.
The family were living in North Street, Oundle, Northamptonshire in 1901.
On the 1891 census the father is a school teacher and the family appears to be living on the school premises, which appears to be a boarding school, Lanston School House, North Street, Oundle, Northamptonshire.
So potentially 2 lower middle class spouses, and similar ages, that sounds feasible.
Ah yes, thought so, found his birth registration, the registration office made a typo error and listed his name as RuBert Edward Sutton.
He didn't die in WW1 nor in England, there are 3 possible death registrations for Edith Sutton, but if they remained with each other, they may well have gone abroad.
Can't see them on any passenger lists though.
