Insulin Pump Pouch Advice

Hi all! Non-diabetic here, looking for advice on a gift for my best friend who has diabetes. (I really hope this is okay but if it's inappropriate I'm sorry and I'll take it down.)

She recently started using an insulin pump and carrying it has been inconvenient. I know there are waist pouches specifically for pumps but she's also pretty fashionable so I was thinking of getting her a trendy fanny pack for wearing out. She's been a little bummed about having to use the pump so I think something cute and not specifically diabetic might make her happy.

Can a regular fanny pack work for carrying a pump or does she really need something specific? Any favorite brands? I'm also pretty crafty so DIY solutions are an option.

Any and all advice welcome! Thanks in advance!
