Imagine if money really did grow on trees, chocolate flowed from your faucet, and every piece of clothing made you look drop-dead gorgeous.

Hang on, there. Now that would be a miracle.

To live the dream, toodle over to Louis Boston and scope out British sophisticate Jane Lewis’s collection, Goat. Lo and behold, the bright young designer, who already enjoys a cult following in London, has a thing for Boston. It’s one of the few U.S. cities where she’s rolling out the line.

The antilabel Lewis is so insistent that her customers actually wear her off-the-rack clothes that she test-drives her samples on a model to make sure they’ll last. But the beauty is, they still fit and look like haute couture: This season’s trousers, knits, and spectacular gowns are made of ultra-luxe wool, cashmere, and silks.

Goat’s sheer simplicity will have you depending on these go-to, stand-alone pieces for any occasion.

Especially picking money off trees.

Available at Louis Boston, 234 Berkeley Street, Back Bay (617-262-6100 or louisboston.com). To see styles, go to goatfashion.co.uk.
