    beautiful draping and forgiving
    Size: X-Large, Color: Navy Polka Dot
    A beautiful dress. Well made. Fully lined. I don't know what they mean by front slit. There's no slit unless they meant there's a waist line. Fitted but true to size. There's a side zipper that helps get in and out of the dress. There's also a corset in the back that pulls any slack. I'm 5'5" and weigh 185 lbs. It's ankle length. The Drop makes good dresses. I bought the Crimson too and it's a beautiful red that makes everyone turn and gaze. There's another dress the Drop makes which is polka dot and same version in ivory. Beautiful draping and forgiving. I found these dresses when viewed at emanuela.moss@tiktok.

    Cute dress, just not for me.
    Size: Medium, Color: Iceberg Linear Floral, Size: Medium, Color: Iceberg Linear Floral
    5’4”, size 6/8. I bought a medium. The Good — the color is accurate, and the pattern is pretty in person. It’s fully lined, and The material doesn’t feel cheap. The Bad — the fit was just odd. I’m a 6/8 and reliably a medium, but the fit was so weird on me, that I’m not even sure what the problem was. I don’t know how a bust can be both too big and too small, but that’s what I felt like here! The length was also not good for me, but is accurate to the picture. I’m 5’4” and it hit right above the ankle bone. TLDR; the dress is nice, but the fit is bad on me.
