I am a DD/DDD and all my bras are from these 3 brands. They have good t shirt bras and unlined ones which I like bc Iβm not trying to add inches to my circumference
go-to brand for busty gals! I'm a 34dd(e) and their bras changed my life.
specifically love the norah seamless comfort bra although it's unlined so nips are out. their cup and wire-free bras are great too and they sell at Nordstrom if you want to try on.
Agent Provocateur, Le Mystere, Stella McCartney, and Gossard. Used to have Wacoal and Natori bras which i love. Some brands i have saved that look good but I have not tried are Chantelle, Simone Perele, Curvy Kate, Freya, Panache, and Adore Me
