What does work uses long channelled underwires, firm cup fabric and a band engineered to carry the weight.
What to look for at HH cup
Depth first: the cup has to contain the full bust without the top edge cutting across. Then the band — it should feel firm on the loosest hook when new, so it still supports once the elastic has relaxed. Wide, adjustable straps set close to the neck stay put best.
