From Bra Maker's Supply:
The Linda Partial Band Bra Pattern features the same great fit as the Classic Bra, but with a different style. This is a partial band bra Pattern, available in almost every size – from 30 AAA – 48 E. This bra has no band running under the cups, therefore, it relies on underwires as part of the support system. If you cannot wear underwires, we suggest the Classic Full Band Bra or the Shelley Full Band Bra. Both of these patterns use optional underwires. This pattern offers great support using Duoplex, Simplex, or other low-stretch fabrics or laces.
