Silver sequin dress from designer boutique in Europe

I got the dress while traveling in Spain at a local boutique size large. I have never worn the dress and I’m just cleaning out my closet. The tags are still on the dress. I paid almost $200 for it .It’s a combination of different colored sequins from light pink to light purple, light green lblue and silver. There’s mesh on the side and a deep plunge mesh. For reference I’m wearing the dress and I’m 5’9 and 139 pounds. I typically wear a size 4 pant or 27 jeans.
