I went to Victoria Secret for the first time in years a couple weeks ago. They initially fitted me at 34DDD which is sister size 36DD. 
Neither of these fit at all. Someone else came to help me in the fitting room and resized me. She said the middle of the bra should basically lay flat on my chest and I shouldn't have any pucker (idk the word but my girls feel like they ate popping out. Pics provided), and that the cup line should be along the bottom of my boobs, not some underneath the wire.  She had me try 34G, which felt alot better but not what she described. I had her look and when I said it still doesnt feel quite right and I pointed out it doesnt lay flat and my elbows kinda bulge out she kinda gave me a weird look and I got a weird vibe off her. She insisted I was 34G and walked away. 
I felt odd about this, but I trusted her cuz I went to her for help. I have wait 2 weeks and just got my bras in the mail today cuz they didnt have my size in store. 
I am pretty disappointed cuz I thin I was right and that these dont fit. I kinda wanna cry. I haven't had a bra fir in like 4 years and was really looking forward to the comfort and support. 
Can anyone help mw figure out if this is the right size and/or if I need a size bigger and what that would be called? 

Bra in pics are "34G lightly lined"
Tap to expand pics, of course. 

I wouldn't know where to begin with returning them for new ones and i took off the tags cuz i thought they would fit. 

Is this bra too small? It feels like it is.
