Q: Can you fit keys and your phone? i wear yoga pts no pockets

Depends on how big your phone is and how many keys you have. I have an iPhone 8 plus and I can fit my car fob and a house key. There are 3 compartments in this bag, so you can put ur phone in one compartment, ur keys (use a small, kinda flat key holder) and lipstick, a few sheets of Kleenex in another, and money in the front smaller compartment. There are several slots to put ur credit cards and driver's license.
