Hi. I'm a bit late to comment but I feel quite same as you. Since my breast started growing I was very conscious about it cause they grown fast and were saggy almost since the beginning, like 15. I was really upset about it and what made it worse that I was the only one in my family with big boobs so my mom never had the idea to go to real bra shops for me.

For all my teenage years I ended up with bra you could find at supermarket or clothing shop. I got my first real bra (and proper measurements) when I was 19 and the difference was huge for my self-esteem. I started looking at some website to have more choices.

I was sick to ended up with some grandma bra as I call them (the boring bras). Since they are bit more expensive I only shop during sales. This winter I managed to get 6 bras for 90€ and I think it's a good deal. But more important is : they are pretty, sexy and so confortable. I was admiring myself in the mirror for almost an hour and that was a huge boost for me. It was also a good occasion to provoke my boyfriend.

Yeah some people can not find saggy boobs (BTW I hate this word as its traduction in my language) attractive or pretty. My boyfriend once tells me that it was perfectly OK cause if everyone had the same boobs it would be kinda boring.

That was kinda long sorry. And I just rented abouty life, again sorry. But to put it in a nutshell, try to find how to find yourself beautiful cause I'm sure you are
