cups (also called cut & sew cups, and multi-part cups) are made with 2 or more fabric pieces. Before molded cups, seamed cups were the only bra cup option. Seaming on a cup allows more variations in cup shapes. Vertical and diagonal cup seams add to the cups support and tend to be more flattering to one's breasts. Seamed cups (especially 3-part and 4-part cups) will always be more supportive than a molded cup. A bra cup with seams can be made out of many more fabrics such as lace, satin, silk, etc. Bras with beautiful details are almost always made with seamed cups. And, if you need subtle altering for a better fit, seamed cups are the way to go.
The drawback to seamed cups is that they may be visible under t-shirts and form-fitting fashions. For this reason, women should have both styles of cups in their lingerie wardrobe.
There are several seamed cup variations:
- This seam design tends to give a more projected and slightly conical shape to the cup.
Vertical center seams
- More commonly found in demi or balconette cup shapes, this vertical center seam is very supportive and gives an uplifting effect to the breasts.
- This seam type is arched or curved in shape, and thus gives a more rounded shape to the breast tissue while also being very supportive.
Back to top
- provide support, centering and lift to the breasts. And the diagonal design (generally starting low in the center and getting higher at the sides) also gives a very flattering appearance to the wearer.
