This is the Alder Shirtdress View B from Grainline Studio. I've made this pattern a few times before (View A, View B, modification), and I think we all know it intimately by now. If you're new to shirtmaking, this is a great place to start as it has a collar and button front but no cuffs, giving you practice with the important bits of the button up before you go the whole way. As a bonus you get a complete outfit when you're finished, as opposed to a shirt, where you may find you still need some pants.
The accent fabric is Liberty London from a long out grown kid's project. With any luck I will not out grow this little piece of it. The roses were pilfered from my community garden (No one said I couldn't pick them. No one said I could.) before I even realized their parallels to the garment.
Alterations: Raised the armhole 3/4". Raised waist 3/4", lengthened the skirt 3/4" to compensate for change and maintain length. Raised bust dart 1" as usual. The biggest modification is the addition of pockets! All that volume and no place to put your phone? Unpardonable! Phone is safely by my side in my very generous pockets.
