This is a video I found earlier on YouTube while I was browsing for some tips on distressing shorts and turning pants into shorts. It's a really good video on how you can put bow details on the back pockets of your shorts. It's a really good DIY if you can find cheap/affordable pants and the outcome really looks cute. Might try this out in the future ;)
