How to make Single Katori / One Piece Katori Blouse with sleeve?

In my previous post, I had explained pattern making of Two Piece Katori Blouse . In this article, I have explained detailed pattern making of a One Piece Katori blouse with sleeve. The Katori blouse is designed based on the natural bust shape of women. The word "Katori" derived from Hindi language means "Cup".

Fabric used:- For making a Katori blouse with sleeve, blouse fabric should be matching to saree. You can use thin Poplin, 2 x 2, Khadi, Cambric, Organdy, Taffeta, Satin, Voile etc. However, is you are a beginner, prefer using Cotton Voile fabric. Since the Front of this Blouse is divided in four parts you can use different combinations of fabrics (i.e. plain, printed, embroidered etc) to get variations.

To make a Katori Blouse with sleeve, all measurements must be taken with great care for precise results. 

Some Tip:- It is very important that you wear your best fit under garment (i.e. Bra) in order to get the most accurate measurements. If you think the bra is loose, adjust the straps accordingly, before taking blouse measurements. 
You can wear a padded bra, though its optional.

Measurements required:- (in centimetres)

1. Length of front - Measure from centre of front shoulder passing over the bust point to 5 to 6 cms above waist line.

2. Round Chest - Take it by passing the tape measure around the body under the armpits. Make sure that the tape at back is over the shoulder blades, parallel to the ground and not loose or hanging at the back.

3. Round Bust - Measure around the body at the fullest point of bust. Do not allow the measure tape to fall at back. The tape should pass on the most protruding part of bust.

4. Below Round Bust - Measure around the body and below the bust.

5. Shoulder - Measure from back neck bone to shoulder bone.

6. Sleeve Length - Measure the length by keeping the measure tape from neck over shoulder till the fullest part of arm.
7. Round Arm - Measure around the fullest part of the arm which is between the shoulder and the elbow.

Complete cutting & stitching of the blouse is shown in the below given video.

Some Tips:- when preparing the fabric for draft placement & cutting:--

1) If using basic woven cotton material, then straighten the fabric by slightly stretching it diagonally to align the warp & weft at right angle.

2) Iron the fabric always to make it crease free prior to marking / placing the draft over it.

3) If you are a beginner, prefer making the draft on paper and then pin it to fabric.

*Once you are successful making a basic blouse you can do variations with use of different neckline shapes for front and back; different types of sleeves; try making with different fabrics like, printed/ embroidered/ checkered / striped etc. Do try and let me know in the comments box below. :)
