Bright colors work well! Especially bright southwesty colors. Reds and yellows and such. I love wearing wearing brighter colors mixed with black jeans/legging, I feel that it looks great!
Also while I am on the topic I only wear button fastened jeans. This just adds a lot of style to any look. I know that it’s an pretty old look and waxes and wanes in popularity often. It has associations with geek chic and “hipsters” – it often makes me think of New York styles.
This seems to be my go-to though lately.
