Such a cute dress for the start of fall!

Loved this dress so much. It is such a great transition piece between summer and fall. Wore with a leather jacket and suede cowboy boots. Such a cute look!

Sexy and Professional!

The fit on this was great! Was fitted where it needed to be and just enough. Received sooo many compliments. Could be a bit of an awkward length though if you're shorter. I'm 5'9 so it hit at the perfect midi length! Wore to a professional event and it worked perfectly!

Comfy Chic

This is a fantastic dress for work and travel. I was able to dress it up for a conference and just as easily wear it with sneakers on a plane. Heavy material but breathes well so found it suitable for most weather.

Fit like a glove. Not too tight in the belly area, so great to wear to dinner. Heavy material for cooler weather, but could be worn in warmer tempts

Super flattering and works for any occasion.

Wore for work in a day to night style (removed blazer for dinner). Love how this dress looked a felt! The material is heavy so it’s best for spring/fall.

Buttery Soft Professionalism

I wore this in my usual size when I was five months pregnant. It was perfect for a winter work trip when paired with a blazer and heels. The fabric was incredibly soft and had enough stretch to comfortably fit my baby bump. It was also thick enough to prevent any visible panty or bra lines.

Beautiful and flowing

I've got too much extra weight around the middle for this to be flattering right now. I put a sweater over it and it was better. Will try again when I'm more fit.

Can hit you on a weird spot

This dress is a nice thick material and would be good for a winter work event. I didn't love it bc of where the pleats it, felt like it highlighted my stomach bc of my long torso

Great work dress

Simple but not basic. Professional but fine to wear to events after work. Super comfortable. More of a knit material, maybe best for fall but I was really surprised with how much I liked this dress. Form fitting but not unprofessional or revealing. Comfortable and not too tight around belly/waist.
