I’m Birdie — Broderie Ruffle Corset Top
Sweet on the surface. Trouble underneath.
A romantic broderie corset built for laneway dinners and rooftop spritzes. Ruffled flutter sleeves frame the shoulders, a soft frill cascades across the square neckline, and the fitted bodice nips in with internal boning and a front hook-and-eye closure. Delicate eyelet detailing runs through the whole thing, finished with a cropped hem that hits exactly right with a low-rise skirt or jeans.
She's the slow walk through the old town. The aperol before the aperol. The top everyone wants the link to.

I bought this expecting it to be good for the price, it is actually one of my favorite outfits The detailing is insane up close. Photos do not even do it justice.

I have owned a few higher end dresses and this honestly shocked me. The weight, the finish, the way it sits on my body, it feels expensive.I actually never to take off.

The adjustability is next level. You can get that exact fit where it is snug but still comfortable all day. I also reached out before buying and they answered everything properly, not some copy paste reply.

No joke, first time I wore it out, someone asked if it was Dior. The weight, the shine, the way it sits... it does not feel like a cheap alternative at all. It just feels expensive.

I wore this to dinner and my friend literally grabbed my body to look closer. She thought it was a designer until I told her otherwise. Insane value for what you pay.
