My favourite combination in summertime would be denim and white for sure. I got this denim skirt from One Teaspoon, which you can shop this brand from various website like Shopbop, Aritzia, Nordstorm and etc. This brand is quite well known for its denim wears such as shorts and skirt.
The top I got from last year from Zara, oh and their online sale for this year has already started. And you can shop for a similar top down at the bottom. Hope you enjoy the post~<3
