Omg thanks for this! I’m on here trying to find a strap for my mini as it hangs annoyingly at my hip and bounces when I walk- I want a shoulder size almost and glad you revived this thread!
I know this thread is super old but I had the same issue as the OP for wanting to carry my micro on the shoulder. I'm also about 5'2". I just found that it juts out awkwardly when carried crossbody and I wasn't reaching for it much as a result. I contemplated selling the bag and buying in mini size, but decided instead to get a replacement strap that's a near perfect match from Mautto. Now it's like my bag has a new life !
