Even allowing for use of a crappy self-cam those pics look years old, almost certainly before lockdown weight could've been acquired, and given her lack of "gym-tone" she's not one to really fight the flab so be prepared for an extra stone or two where they aren't most welcome.
Someone only 27 would not have a phone with such a crappy selfie camera, allowing for the poor quality cam and filters I'd say she's at least mid-30s and she'd have to be using a handset that was either well over 5 years old or really (really) cheap.
Any profile that includes "High Class British Escort" should ring alarm bells, especially if she ain't using a bling phone to accessorise her "high class" (self-)image.
