Thank you all! I'm glad you like it.
Quick tute, handy for boobage-addled women.
First, take the measurements:

Measure front and back separately. For the front measure as follows:
Waist A
Widest part of bust B
Distance waist-bust (measure level with nipple) C
Distance bust-top of chest (level with armpit) (level with nipple again) E
Distance chest-shoulder (again level with nipple) F
Widest part of hips G
Distance waist-hips (level with bellybutton) H
To make the front pieces, fold the fabric in half lengthways. Take our waist measurement A, halve it, and add several inches. I added 4, but you should add more if you want it to wrap further or have more tummy, or less if the reverse is true. So, we have (A/2)+4. Draw a horizontal line of this length from about 1 inch from the fold, to allow a seam allowance.

Draw a line of length C up from this. Then from that line draw (B/2)+4

Next add E and F together and draw a line up about 2 inches in from the edge of the bust line

Follow this in horizontally about 4 inches, then draw a diagonal line down to the waist line.

Draw a horizontal line level with the top of the chest (level with armpit) and take it out to the same distance as the bust line.

Next, draw H, and from this draw (G/2)+4

Neaten the lines up - connect them, adding curves as needed for the bust and armpit.


Now you have the pattern for the front piece.
For the back:
This is much simpler.
Measure as follows:
Waist A
Upper back (level with armpit) B
Shoulders C
Hips D
Distance waist-back (level with spine) E
Distance back-shoulders (level with spine) F
Distance waist-hips (level with spine) G
Divide A, B, C and D by 2. Fold the fabric lengthways. Add together E, F anf G and draw a vertical line for these. At the appropriate points, draw A/2, B/s, C/2 and D/2

Connect the lines, adding curveswhere needed.


This is the pattern piece for theback.
Cut out 2 each of the front and back pieces, connect them all together but do not join the 2 front pieces.
When connecting one of the front pieces to a back piece, leave a gap about 2 inches wide level with the waist. Ensure the gap is secure and will not widen by stitching back and forth either side a few times.
Use readymade or own-made ribbon, connect a piece level with the waist to the edge of both front pieces. Add trim as desired. Finish sleeves.
TADA!
