Description

The Bonn Shirt and Dress by Itch-To-Stitch is a fashion staple that can transition between the seasons making it a wonderful addition to any wardrobe. Both the shirt and dress are designed with separate pattern pieces for five different cup sizes with bust darts for a perfect fit. Four different sleeve options (long, 3/4, short, and flared) can be combined with either the shirt or the dress version.

Sew the dress up in chambray, for a classic garment that can be layered over and worn all seasons. Or make the shirt with long sleeves in rayon challis that you can wear to a dressy dinner.

Additional Notes

This PDF pattern includes all pattern pieces and step-by-step instructions with illustrations.

The pattern is well drafted and the instructions are thorough. I love that the placket facing is integrated into the front pattern piece - saves time on cutting. I also love the shape of the neckline and the mandarin collar. This is a great pattern!


A really detailed pattern with images for each step. I especially loved that you could print only the size(s) you needed.



Great pattern! Well drafted and I love the different cup size options!



The instructions were very clear and extremely easy to follow. I made a small adjustment to shorten the dart and did a full bicep adjustment but that is all it needed. Very pleased with the fact that I could choose my cup size and did not need to do a fba.


For being a button shirt/blouse, this pattern is pretty easy to put together. The only part with a bit of difficulty is the collar and the instructions are written so well, that you get through it in no time!


This may be one of my favorite patterns yet. The fit of this pattern is very flattering. Kennis includes custom front bodice pieces for different bra cup sizes A-DD, so no need to perform a small or full bust adjustment if you're something other than a B- or C-cup. The front facings are cut-on (attached to the front bodice, then folded over), which creates a very clean and fiddle-free finish. I'm extremely impressed with this pattern and the instructions, and I highly, highly recommend it.
