Which colour do u think I should buy my lingerie?

Hi team,

I’m wearing the below Sat night I’m going to a dinner and a church outing and I’m 12 weeks preg... lol hence still a small waist 6... n a big bust at size 12 n a size 12 top I’m wondering should I buy white lingerie, black, black-purple or black-green... I’m visiting the store Thursday and I’ve got my best friend not coming with me she’s sick do u guys think with a white bag n shellac nails n white flat pointies I can still go white under? Or should I be adventurous n say black purple or black green, bear in mind I wear a black maternity bra always and I wore red at Christmas...
