Lingerie advice?

I want my boyfriend to feel more desire for me. The last time I tried initiating anything he just ignored my advances and I felt kinda humiliated and dumb for wanting him to want me back. I see a lot of posts about girls surprising their partner with some nice new lingerie to spice things up, so I wanted help on choosing a set of lingerie! Im very petite, small boobs, wider hips, pale, brunette pixie cut hair, sharp features. Anyone got any ideas for what kind of styles might work for someone that looks like me? Any pictures to show? Anyone with a pixie cut find a lingerie style that compliments their hairstylr? I feel like my short hair eliminates any femininity about me, so I dont really feel like I can pull off anything sexy.
