Would a wired bra be beneficial for 38DD or should I stick to wireless?

Recently I used the ABTF calculator to determine my bra/cup size, and discovered i'm around a 38DD/DDD in the US/CA sizing. I've never really known what my bra/cup size was because all of the bras i've ever own were in xs-xl sizing, and I was usually around an xl.

All of the bras I own are wireless, padded bras by Warners. They're comfortable but they don't really give me support, they just kinda smoosh my breasts together and after a few wears they get loose around the band. And now knowing that I'm around a 38DD, should I look into a wired bra for support and to prevent sag? Or should I look into a different type of wireless bra?

Any and all advice/recommendations are welcomed
