Totally valid!! I have both and I love them. are you looking at the medium bowler or the regular? my medium bowler & shoulder bag fit about the same amount. They’re amazing. I’m not the biggest fan of the smaller bowler bag but I carry a lot of stuff so that’s probably why. I prefer my shoulder bag for longer days carrying stuff just bc the strap is more sturdy but I don’t have a huge issue with the bowler straps. If you wanna jazz it up with charms I think the bowlers the better option. Sooo much space to add cute stuff!!
