I love the 3364; we go back a long way together! The 32D in this model (size now sadly discontinued) is, believe it or not, a perfect fit to my 30F frame. I wore these exclusively (and I mean exclusively) for eight years, until my recent professional fitting opened my eyes to other possibilities.
Since the 32D was discontinued, I buy it in 34D and alter the band. The underwires are a tad wide, but I can live with it. It's still a terrific bra despite facing stiff competition from the newcomers to my underwear drawer!
The measurements posted are for an unaltered 34D bra. I've left a more detailed review of this bra in the 32D.
First off, a word about Wonderbra... although one and the same company, a "Wonderbra" means something very different to Canadians than to the rest of the world! Here in Canada, a Wonderbra is usually a no-nonsense, softcup bra. They come in boxes at department stores and generally cater to an older clientele. Just imagine my amusement when I found out that in the UK, Wonderbra is synonymous with plunges and push-ups!
The 3364 "butterfly" minimizer is a wonderful coincidence of inconsistent sizing. The 32D is, believe it or not, a flawless fit to my (usually) 30F figure. For the last 8 years, up until ...my recent professional fitting epiphany, my bra collection consistently solely of 3364's. I loved them to pieces. Simply nothing else in the entire mall fit right.
This is a fantastic bra. Since it's a minimizer style, the central gore is very wide and not designed to rest against the sternum. The shape it gives is gorgeous -- uplifted, rounded, subtly minimized, and with just the slightest hint of cleavage. Under clothes, it's indistinguishable from my Fantasie Esme. The 3364 has soft and satiny cups, and I love the butterfly detailing at the center.
Tragically, Wonderbra discontinued the 32 band size years ago. For a time, I could buy the Bali 3364 (exact same bra) online, until it too was discontinued. Today I get the 34D and alter the band to fit. I'll review the 34D separately
Pros: - Great shape and uplift. - The most extraordinarily comfortable bra ever. - Price! Since Wonderbra is a Canadian brand, they are inexpensive here. Since Canada slaps tariffs on imports, we pay an arm and a leg for UK bras.
Cons: - 32 (equivalent to a 30) band has been discontinued.
