The LB Pullover from Paper Theory Patterns is available in sizes 6-28, with the size 28 being a 56″ bust and 57.5″ hip. Currently Tara has released her Kabuki Tee, Miller Trousers, Zadie Jumpsuit and this LB Pullover in her extended size range (and her website tells me that the Olya Shirt is coming early 2020)!
Tara has studied fashion design, and so is trained in pattern production so I’ve always found her patterns and instructions to be very exacting- no confusing instructions, no inexplicably shoddy finishes, notches always match, and I think she also does a great job for plus size bodies too (which is obviously an important consideration).
Size details: My current measurements are around 47″ bust 44″ waist, 56″ hip and between and 18-19″ bicep. I cut a size 22 neckline/bust and graded out to a size 26 at the waist and hip. The sleeves I cut in size 28 (the largest size).
The pattern had small amount of tapering in below the armpit, and the adjustments to the size basically meant that I cut straight down from the size 22 armscye and where I was supposed to turn in, I cut straight down, meeting up with the size 26 line. Oversized tops can end up looking less-than-optimal if you have to grade out too much from the bust (because your grading out can cause a kind of trapeze effect around the hem).
