This jumpsuit is amazing. I have made one before but found it difficult to get in and out of, not so with this one.

It reminds me of a WW2 siren suit. These were all in one garments which everyone wore over their normal clothes to keep them clean as air raid shelters were filthy. They were also quick to put on at night over nightwear. Sir  Winston Churchill wore them, but his were hand made by a Saville Row Tailor!

The fabric is Robert Kaufman Chambray which is divine to sew with and to wear. I decided to add contrast facings and handmade piping to lift the fabric. For this I used a cotton fabric interfaced with a medium weight interfacing on the facings. 

The pattern is McCall's Pattern M8046.

A word of warning, I am just short of 5'5" and the pants were only just the right length with a very narrow hem so you may need to add a few inches to the trouser hemline. Also if you have a long body then consider lengthening the bodice slightly too.

The pattern is very straightforward to make with good instructions. 

To add a bit of colour to my outfit I made some covered piping. This is easy to do by cutting out his strips and folding them over piping cord.

Then I inserted it between my fabric - in this case the back bodice and used a zipper foot to get really close to the cord. It is easy to feel where the cord is and to stitch very close to it.

This is the back bodice.

I also inserted piping along the pocket edge.

Another change I made was to alter the sleeve length. I cut the sleeve pattern piece to elbow length and then formed a turn up by measuring and folding the fabric. The turn up will be held in place when the sleeve seam is sewn.

Other places I added contrasting fabric was the collar underside and the front facings.

I also lined the pocket but you cannot see that.

A final touch was to make a handkerchief and sit it in the pocket.

I was wondering how to make the belt and I came across some D rings. Two of them stitched into the belt end make a really nice, simple belt closure which stays closed.

This is a great pattern, it has a few variations already but it can be altered in lots of other ways too.

The fabric is fabulous. It washes well, it is comfortable to wear, not too heavy or too light, creases minimally , what's not to love?

This fabric is suitable for many other garments including children's wear so do please consider what you will make with yours.
