I, too, would love to know of a dupe for "Berry Boost."
This, from a person whose collection includes MAC Rapturous and Rougette Mattenes; MAC Dare You, Wild 'Bout You, Dubonnet, and Rocker; as well as Illamasqua Salacious, Shard, Atomic, and Magnetism.
NONE of the above is an exact dupe for Berry Boost!
However, Inglot recently released a collection that includes five new berry-toned shades, so that might be worth investigating.
