Baggy dungarees cropped like culottes – two for one!
Dungarees: Vintage. More wide leg faves: Asos, Free People (love these whites!). A skinny version if you prefer by Madewell (on sale). Top (worn back to front): Urban Outfitters. Trainers: Adidas. Shades: Ray-Ban Clubmasters. Bag: Chanel. Similars from Forever21 and Saks.
I found these ones at a vintage boutique in the east village but I feel like you can get ones like it on eBay.
Checking the men’s denim department too in shops and cutting a pair to above the ankles gives the same effect!
