Which bra sizes should I try?

(this is a repost because I posted the other one when most of you were probably asleep - hence the screenshot of the photos)

I'm wearing a 36D in the photos but I've lost around 5kg since my last fitting.

The middle is flat on my chest

The strap at the back is in the correct place

The wire doesn't dig in

My only problem is my boobs don't fill the cups anymore :'( I'm too busy to go out and get fitted etc so I'm going to order a lot of bras and return all the ones that don't fit perfectly.

Which sizes should I try?
