Scared to dress up

Hi guys I just need an opinion my boyfriend finds it very hard to express his feelings and I have really low confidence as in I overthink things to the point I won’t do it o bought lingerie for valentines but I don’t know what to do do I just walk in and stand there or how do I go about it I’ve taken some pictures please dont judge I was going to send him the pics and say I have something for you for valentines but like we’ve been together so long will he even think it looks good or just think I know what her body looks like anyways is it cringey if anyone has an tips that would be great thanks!
