I love being a student in the finer points of bra-fitting, but once in awhile I need a respite from the underwires and the structure. One of the things I love most about this pattern is that it is very easy to fit with a few simple adjustments.
Over the next two posts, I’ll walk through a few common pattern alterations. These might help some of you who have already made the Watson or want to make a quick test bra during the sew along. Today I’ll focus on the bra but I’ll be back after the weekend with a few bikini suggestions, too!
Marking Your Pattern
Because bras use such precise seam allowances it is a good practice to mark in your seamlines. I often stress this, since fudging 1/8″ here or there can add up in a bra.
When you make adjustments, you’ll be making them from the seamline. Afterwards, fix or true the seam allowances for these new seams. On this bra, all seams are 1/4″ (6mm) EXCEPT the band hem, which is 1/2″ (13mm) and the strap fold line, which is 5/8″ (16mm).
Marking the seamlines can also help you remember the elastic allowances or change them. For example, if you want to use a 3/8″ (10mm) plush elastic at the top of the band, you add an additional 1/8″ (3mm) to the seam allowance on this pattern. If you wanted to use fold over elastic at the neckline, you’d remove the 1/4″ allowance.
Measuring for Straps
To find your best strap length, measure from your shoulder to your bustline and multiply this measurement by two. The result is one strap length, and you need two of these. It may need to be shorter, depending on how high the cups are on your chest, but you can refine this length later on.
Fitting the Band
This pattern is drafted for a fairly firm powernet with about 35% stretch. If you are using a lighter or stretchier band fabric–such as stretch lace, lycra, jersey or a lightweight stretch mesh, this may result in too big of a band fit.
If your band is too big you can try one of the following:
- Go down a band size or even two sizes.
- Double your fabric (but test the stretch of your fabrics when doubled).
- Try a stronger band fabric.
- Adjust your band pattern piece.
Adjusting Band Length
You can determine how much you want to shorten the band by pinching out the excess and measuring the amount you pinched. Or you can adjust your band with a little math! Remember that you only need to adjust your band piece by half of the amount you pinned out, since there will be two of them.
Adjusting Angle of the Band
If you are experiencing gaping along the underarm, you may need to adjust your band so that it is shorter along the top.
If the bottom of your band feels too tight but everything else seems to fit, the band may be too angled for your body shape. You may notice this particularly in the longline bra. You can adjust the band so that it is longer at the hem:
Adjusting the Strap Position
In the front of this bra, the straps should be quite centered above the breast, going to the middle of the shoulder.
If you find that your straps are sliding away from the middle of your shoulder (or sliding off your shoulder), try narrowing the strap distance in the back.
Adjusting Cup Volume
If your cups are too big, you’ll notice wrinkling in the cups.
Many times these will look like vertical wrinkles in the top half of the cup as the breast settles in the bottom of the cup. If this is happening to you, your cup has too much overall volume for the fabric you are using and I’d recommend going down a cup size.
If the ripples are minor and you are happy with the overall fit of the cup, you can simply take in the cup seam, much like you’d take in a princess seam. You want to take in each seam equally on both sides in order to keep the seam lines the same length. This adjustment will flatten the curves a bit:
Tip: There’s no need to get fancy with your curves; stretch knit patterns need very simple lines.
Lowering Cup Height
If your cup is too high on your chest AND you have wrinkling in the top of the cup, first try going down a cup size. However, if you are fully filling out your cup and the cups are still too high for either taste or proportion on your torso, you can try lowering the height of the cup. First mark in the strap fold seamline, which is 5/8” from the top of the cup and cut away this part:
Try moving the strap attachment seam about 1/4″ but no more than 1/2″. There is a limit to how much you can lower the cup before the strap attachment point starts landing right on top of your breast. This bra has triangle-style cups that are meant to go all the way over the top of the breast.
These are the most common adjustments I use in bra-making but if you have a particular fitting question not addressed, don’t be shy about asking!
