Last week we covered the importance of stabilising the bra and how to go about it.
This week I began developing the pattern for the halter top that would be attached over the top of the bra. This is a great way of adding base pattern before adding trims and embellishments which can really add to the finished look.
To begin pattern drafting you will need some scrap fabric – begin by pinning this to the bra in the same way as the interfacing layer starting in the center and working your way around each upper edge of the bra and darting where necessary. As I was creating a halter style bra I found the next step much easier to complete with a mannequin, but using the client would be just as beneficial if not more so. It is important that the halter straps lie at the correct angle to fit comfortably around the neck.
Once the scrap fabric is pinned flatly to the bra you need to begin marking out the shape of the halter as there are many different angles and curves that could be used. With the halter section it was necessary to shape the beginning of the straps so that they would taper down from the neck strap in one smooth curve. After you have decided on the shape the fabric can be cut along these lines and around the cup shape giving you a feel for the final design.
Next it is time to consider the back straps. There are a few ways of approaching these but for this design we have chosen to go with straps that tie at the centre back. This style is easily put together and allows the costume to fit regardless of weight fluctuations. From the edge of the cup the strap can be either straight or shaped depending on the style you want.
Make sure not to make the back straps too thin especially if the costume is going to be weighty as much of the weight will be carried by these as opposed to those around the neck.
This completes the drafting of the pattern, so all that is left to do now is to remove the fabric from the bra marking all the darts so that they can be easily transferred to the paper pattern for cutting.
Lay out the scrap fabric template on to the paper and pin it in place to stop it moving around. Transfer all the darts and trace the outer shape on to the pattern paper, this will give you a nice easy to understand pattern to work from. Once all this is done you will need to add seam allowance all the way around both the main bra and back strap pattern.
It is important that the back straps are separate from the main body of the bra as they will take a lot of weight in some cases and therefore will need a lot of securing. The best way of doing that is to stitch it on to the casing that holds the underwire. These are designed to take the force of the back straps supporting the bust, but I’ll cover this more thoroughly next week.
If you have any questions about bra pattern drafting get in touch, I’d love to hear from you.
