Sorry, I have no girl family member to help me out.
Okay, I found a Victorias Secret bra size guide and I didn't have a tape measurer to help me out so I did the best I could with a ruler (Like I measures front of my chest, back, etc. and added them together. I did that both for the band and cup size) and I followed all the instructions and it came out as DD and I was like heck no! My "chest" is average size for my age so that makes no sense at all. I must have done it wrong because I have no tape measurer, haha. So could someone please tell me what the average size for an 11 year old is? Thanks in advance.
Lol I'm still in training bras, I'm just preparing for when I need to make the switch. And I don't shop at Victorias Secret, I just went on the site to see my measurements.
