If you’re like us, you’ve probably wondered what everyday stuff famous people add to their carts — like hair spray or an electric toothbrush. We asked actor and singer Ben Barnes — whose debut album, Where the Light Gets In, came out earlier this year — about the home-speaker system, digestive biscuits, and cropped tees he can’t live without.

I do a wardrobe cleanse every few years because I have too many choices and too many things. I’ll invite some of my pals over to take whatever they want, and then I take the rest to Goodwill. When I was getting ready for this most recent tour, I just wanted a new black T-shirt and a new white one, just to have basic things. I think the photographer on my tour suggested these. And I was like, Wait, cropped is the best thing for feeling confident in my outfit. That was a relatively new epiphany for me — that that’s the way that I like to look. The faded black one is the one that caught my eye and the one that I wear the most. It has the correct shortness by the waist and slightly bigger shoulders without having your arms swim in the giant sleeve. I also have one of their green check flannel shirts, which has the same cut at the bottom, which is great.

I came across this online five or six years ago maybe, and I struggle to talk about it without sounding like I’m doing a commercial for them. I used to get headaches, I think particularly from moving to California. The way that the bottle functions just made me want to drink more water — it’s something about the straw. It’s something that I always have with me. If you go online, some fans of mine have set up accounts called “Ben and his Owala” or something like that, and you can find dozens of pictures of me, like onstage with my band or doing meet and greets. I’m getting into advanced Owala territory where, because I’ve got more than one, I’m starting to change the lid and base combos so they can be unique to me, which is ridiculous. Maybe not the person I need to be in my life, but there we go. That’s what’s happening. I did find myself saying the other day, I need to get this new color. You drive through L.A. and you see people lining up ’round the block for new sneaker drops, and you roll your eyes at it, thinking how ridiculous it is. Apparently that’s me for these water bottles.
