Perfect dress
I’ve been eyeing this dress for weeks and finally caved and thank goodness I did. It’s now my go-to for events where I want to look put together but not overdressed.
Happy me!
It’s so beautiful 😍 I went with the smallest size and my measurements are Bust: 33 inch, Waist: 25 inch, Hip: 36 inch and I am 5’1. The sewing is of very high quality and for the price you pay it seems expensive. I would highly recommend
Quality and looks are insane
Honestly the prettiest white dress I own. The fabric has a beautiful flow to it.
Date night
Took this beauty for a spin on a date night and let’s just say… he couldn’t take his eyes off me.
Fancy
This dress is everything I was looking for—flirty yet sophisticated. The ruffles are a lovely touch, and the lightweight fabric makes it comfortable to wear all night. The cowl neckline gives it a romantic vibe. Ideal for a fancy dinner.
