Lingerie for my body type? ๐Ÿ˜“

I've never worn lingerie before, but I want to because my SO has hinted that he would love to. I'd love to wear some for him and feel sexy about myself but I feel like my super skinny body will make me look silly. ๐Ÿ˜ž I've always struggled to keep weight on and I've gotten to the point where ive accepted myself but I feel like lingerie will be a step back lol. I have absolutely no butt and it's embarrassing because he will try to pinch it and his fingers always just slip off my skin ๐Ÿ˜‚๐Ÿคฆ๐Ÿผโ€โ™€๏ธ๐Ÿคฆ๐Ÿผโ€โ™€๏ธ My best feature would be my boobs, somehow I manage a 34b. ๐Ÿ˜’

Any advice? What might look good on girl who's 2 dimensional? ๐Ÿ˜‚๐Ÿ˜ฐ
