I carry a canvas tote EVERY summer! One's a Marc Jacobs green canvas and leather and the other is a coated canvas Gucci. Both are pretty old but still in great condition. I hate perspiration issues during the warm weather. This year I also bought an Orla Kiely summer bag. The only leather one going with me this summer is my new Asos (PSI lookalike). The light colour is right, the price was right, let's hope the leather wasn't a big mistake!
I realized the swamp that calls itself my city is not the place to carry leather (much) during the summer. I have a striped RM MAM in canvas with leather trim that is my main bag for the season.
I have several cute canvas totes I love for days I dont want to "mind" my purse . I really want a straw tote for summer, but the ones i like are all $100 or more...eh I wont get THAT much use out of it
The Ivory Steve Madden Nantucket tote has been my go to summer bag for 2 years and I just got the Etienne Aigner shoulder bag for a little bit more color.
I have a small canvas taiuti tote for summer. has a really beautifully printed bright floral pattern. I just chuck my phone, a book, wallet, and a bottle of tea and i'm ready to go.
