Katherine Hamilton are a guest brand, UK-designed fuller bust sets in beautiful laces. Their bras feature a custom-designed underwire for fit, comfort and forward projection.
The Abbie balconette bra has a 3-part cut and sewn lace cup over a sheer "tan" stabiliser layer, with silk underbust trim and straps and silk-covered buttons to add a luxurious edge. The shape is rounded, lifted and projected (pushed forward). The decolletage has an eyelash lace trim.
Please note that KH use the "+0" method of sizing. This means whatever your underbust measures, that is the band size. Then, as usual, every extra inch on the overbust is an extra cup size. So, for example, if your underbust is 32 inches, and your overbust is 38, you would choose a 32E.
If you are used to US bra sizing, they recommend going up by one cup size compared to your usual.
