Kaei&Shi Floral Embroidered, Underwire, G-String, Garter Belt, 4 Pieces Lingerie

Size 8 - 10 is equivalent to M?

Why are the pics so deceiving? i saw this by chance. all the pics are from honey birdette lingerie, which are $300+ (which i have).

What size would fit a 38DDD best?

I ordered size 4-6 on a prayer hoping the bra was a “0-2” lol. i have an a cup but wear medium or (4-6) on my bottom. what should i expect?
