Folks, My fiancé was kind enough to get me a cashmere sweater from JCrew for a Christmas gift. Since then I've ended up losing 20 pounds and now it fits more like a bathrobe (there are worse problems out there I guess!). Is it possible to alter a sweater? Can any normal alterations tailor handle it? The length isn't an issue, mostly the waist. I've included a picture of the pattern if it helps.
