I recently took a trip to Paris and then London for a few days. In fact, I just shared a list of the elevated basics I noticed Parisians wearing on repeat during my trip. I thought I'd expand on the fashion moments I saw with the specific outfit formulas I spotted in both Paris and London.

Of course, I saw a range of inspiring ensembles, but there were two specific looks I seemed to see in some iteration every day. In Paris, I noticed chic looks that featured relaxed pants, a button-down shirt, and typically flats.

Seriously, this look was everywhere. In London, I certainly saw this same easy yet forward look but also noticed so many people wearing flowy midi or maxi dresses and sneakers or sandals. I saw this two-piece outfit formula in every London neighborhood.

Below, you'll uncover visual inspiration showcasing these two looks. I also included shopping recommendations for your reference.

This is a perfect example of the outfit I saw on so many Parisians.

The relaxed button-down shirt combined with the loose trousers is so effortlessly cool.

There is something so elegant about this simple ensemble with the shirt and trousers. The belt is another nice addition.

Into the layered look? I also spotted many French women wearing an oversize button-down shirt over a tee or tank with wide-leg trousers or jeans.

The London look I spotted with the flowy dress and easy shoes is just so chic. This ensemble is particularly noteworthy with the fun sleeves and sneakers.

Go bold with a colorful dress and trend-forward sneakers.

The cardigan over this flowy black dress is absolutely adorable.

The socks and slides are also fun.
