How to convert LV Toiletry 26 to a crossbody bag

I bought the new toiletry 26 bag from Fashionphile and I really wanted it to be a bag. I am both of these:

1. A Klutz and I spill. (I needed an insert organizer that protects the bag from blush and pen marks)
2. TBH I wasn’t using the toiletry bag as a toiletry bag
