Swatched side-by-side the two are nearly identical. I'm really ( reaaallyy ) bad at describing colors but Riri Boy is slightly plumier and the Revlon lippie isn't quite as pigmented. On the lips you can barely tell a difference though.
Obviously M.A.Cs infamous lippie has longer staying power since it's a retro-matte ( 5+ hours ) and has that infamous "Riri" signature imprinted on the lippie. But don't get it twisted Berry Haute does a great job too with 3+ hours and I just love the gold packaging. So chic.
( T - B) M.A.C Riri Boy, Revlon Berry Haute
Me being the lipstick feign and Rihanna junkie that I am, I'm so happy Riri Boy has joined her sisters and am still on the hunt for a couple more babies from the Riri X MAC collections. But if you're a beauty on a budget, Berry Haute is the way to go. Have a fabulous dayyy. <3
