From Knitty article:

There once was a kiddo sweater called Boo.

A bunch of grown-up girlies said “Me, too, me, too”.

Let’s cheer for the nipped waist and vertical stripes that give it sass,

But do, please, hold your comments about the ruffles framing my big fat ass!

Two colors of Noro Silk Garden and a 2x2 slip stitch transform chunks of horizontal color into an intriguing vertical pattern. The ruffles, as always, are just for fun.

The slip stitch pattern makes a heavy-ish coat-weight fabric. This is not a pattern for my pals in South Texas; sorry, gals.
