What do middle aged women wear in Europe, specifically Berlin and London?

My mom and I are traveling together to Berlin and London in August(I like to plan ahead), and I prefer we both avoid looking too much like a tourist as it makes you a target for pickpockets and alike. I have a pretty heavy interest in alternative fashions and last time I was in London, when I was 14, I blended right in and I’m fairly sure that my more matured(I’ll be 17) sense of style will still blend in, especially as I often explore European street style sites for inspiration. My mom and I, however, have noticed that her style is much more Western, although she doesn’t wear anything “typically western” like baseball caps, sneakers, baggy clothes, her style is largely composed of olive green shorts/capris, kahki type bottoms, denim skirts and printed blouses(florals, mostly) with leather shoes or sandals.

Will her style suffice or will she stick out like a sore thumb?
