Continuing on with fitting adjustments, today I’ll walk through some possible alterations to your cups.
Some tips for working with these alterations:
- Mark in your seamlines on your pattern so that you can measure exactly how much you want to adjust.
- The best way to determine your alteration is by pinning out excess along the cross-cup seams, neckline or arm edges of the cup to see if that helps things fit. If you need more room you could cut a bit into areas of your tester bra to see what alleviates tightness. Measure how much you needed removed or added and write it down. I keep the pins in the bra so I can measure my little “darts” after I take it off.
Overall volume adjustment
If you simply want to add or remove more overall volume in the cup, pinch out darts along the main seams until the cup feels comfortable. Measure out this amount along the cross cup seamlines. Spread or close the dart and redraw the seams.
I’m just showing one adjustment right at the bust point but if you are adding or removing a lot of volume, you may need to make several little darts or slashes along the seams so that you make an even shape adjustment across the cup.
Adding or Removing Lower cup volume
If you notice excess fabric pooling at the bottom of your cup, you may need to remove some of the volume from the lower cup. Pull up the lower cup and see if you can pin some of it out. This adjustment could also help lift the cups.
You will have to adjust the length of the uppercup seamline to match the new lower cup seamline. The illustration above shows one way to do that, by cutting and overlapping to shorten the seam.
Smoothing the apex
If the cups are just too (yes I’ll say this!) pointy, you can always smooth out the apex curve of the cup. When doing this adjustment, start small so you don’t remove too much of the seam length. This is pretty similar to doing the above adjustment. Maddie of Madalynne has a great post explaining cup alterations, particularly this one!
Both of the above adjustments will add some lift to the bra in some way. If everything fits and you still want a bit more lift, you can try flattening the seam of the upper cup. The flatter this seam is, the more lift a bra has. (Balconette bras with 3-piece seaming often have a totally flat upper piece.)
To make this adjustment work, you will have to remove some length on the lower cup seam so that it matches the new upper cup.
Gaping at the Side of the cup
Pin out the excess along various points of the cup to determine where the excess is. Transfer this to your pattern by slashing and closing the darts, as in the examples below.
Adding underarm coverage
This is an alteration I did to my bra. It could help if you want some extra coverage or support along the side of your cup, depending on your figure. This alteration requires both your cradle/band and the cup pieces which run along your underarm.
Line up the cup pieces and cradle right along their seamlines.
Draw in the new underarm line starting from the band and going up toward the cup. In this illustration, I’m also making my straps further apart on the top of the cup.
Adding more coverage the top of the cup
If you have more breast tissue at the top of your cup and want more coverage, you can always raise the top seamline. Most of the patterns we are using aren’t entirely a “full cup” bra.
This new line can be either totally straight or just slightly curved–a curved line will add a bit more length.
That’s it–I hope these give y’all some good ideas! Tomorrow I’ll be featuring some of the great fitting questions you had for Norma.
