MobFell, UnderFell and Undertale seeing their S/O in a more fancy outfit but they're self doubting how good they look
Smoke (MF!Sans): He would immediately dial in the flirts, complimenting you left and right, but as soon as he realizes you’re uncomfortable with how you look, his surface level flirts would get a little more.. Personal. He loves to tease, but its important to let you know that your attraction is far more than just the outfit.
Doom (MF!Papyrus): Upon fist noticing you in such a fancy outfit he begins to blush, circling around you to examine every detail. He doesn’t realize you’re doubting how wonderful you actually look until you mention it. Immediately he offers to buy you something to better suit your tastes, and purchase a tailor for you to find something that even you find flattering.
Scarlet (UF!Sans): Seeing you in such an outfit is amazing, he himself rarely wears fancy clothes and it is a treat to see you in something so dashing. But seeing your nervous expression, he can’t help but dial in give you all the affection you could ask for. Pointing out every detail he loves about you until you’re a blushing mess.
Vermillion (UF!Papyrus): He loves seeing you in fancy outfits, but he’s surprised to hear you aren’t exactly comfortable wearing something so.. high class. He would claim, “NONSENSE” before ranting, even writing down a list about how much he adores you in such an outfit. Before split second deciding it’s a perfect night for a date.
Sans (Undertale): Sans never dresses up, even if his brother insisted the most he would ever wear is a tuxedo print t-shirt or a tiny bowtie with his usual comfort-wear. But seeing you in such a fancy outfit is a sight for sore eyes. He proposes a little date between the two of you if you’re going to dress so fancy. You barely get to exclaim that you don’t particularly like yourself in an outfit before you both are eating mac and cheese by candle light and watching some funny memes. He notices your dislike, but would much rather you enjoy yourself instead of focusing on what you don’t like about yourself.
Papyrus (Undertale): He’s excited to see you so dressed up, getting so excited that he rushes up to his room to change into his own set of fancy clothes, (which is really just his ‘date outfit’ with a tank top, basketball shoulders, and a backwards cap). Before you can even express your displeasure with how you look, you both are eating dinner in a fancy restaurant that for some reason he had reservations for. By the end of the evening, you can’t even remember what you were upset about.
