Fashion Frenzy is more of a bubblegum pink (or as the website described it: "mid-tone blue pink") and it has almost no shimmer if any at all unlike like Dollymix. Dollymix is a hotter shade of pink. I suck at describing things haha HTH!
Yeah Fashion Frenzy is a blue toned pink - bubble gum pink with no shimmer but it is bright in color whereas Dollymix is a darker warmer pink with shimmer.
