Lingerie help? U.K. BASED PREFERABLY

Hey! Fun fact - I’ve never really owned what I would consider lingerie, at most I have had a somewhat matching bra and knickers (that I very rarely even wear together).

My boyfriend and I spend half of the year long distance, and he is due to leave soon for a few weeks, I want to buy something and surprise him before he goes but I have no idea where to start.

I just wanna say that I’m a size 14, with barely any boobs (I’m a half full B cup at best) and I hate my stomach, more so the bottom part. I’m also on somewhat of a budget with being a student, so I’m looking for somewhere as cheap as possible without skimping too much on quality.

I just have no idea where to start and what kind of things to look for. It’s so hard when all of the models are skinny and gorgeous and I know it wouldn’t look anything like that on me.
