Even on a 7 month pregnant person :) loved the stretchy fit.
Very flattering and great staple black dress. Looked good with a lot
I love this one. The fabric has a lot of movement and walking feels dramatic.
I wore this dress on the fourth day of a work conference, it was comfortable and elegant and moved beautifully when I walked. I got multiple compliments and one woman said I even had a “coastal vibe” which may have been the shoes I chose. I wore a small, but because it is so stretchy, the XS would have also worked great
Wore this with my jean vest. It was long but very stretchy and comfortable. The vest was because i wore it to work, and the neckline is low. Super flattering for your figure. Gives that hourglass shape.
Fit well but nothing special. Didn’t love material. Bought it for a birthday dinner and it wasn’t right for that - ended up just wearing it on a date night
Second time renting this. Fabric drapes beautifully and is super flattering. Runs a tad large because it's very stretchy. I'm very small-chested and felt this was conservative enough for work. That might be different if you're curvier, only because the neckline is fairly generous.
This is a simple dress, but it has a real WOW factor. Very flattering and comfortable. The neckline hit in the right place and it has some stretch.
Loved how easy this dress is--a little stretch makes it easy to slide on. Could feel really dressy with elegant heels, but I wore it with sneakers.
Loved this LBD
This is nice enough to wear to a nice dinner, but still incredibly comfortable for waking around. Bought it because I know I’ll wear it often.
I wore this for a work meeting 24 weeks pregnant and loved it! It's light, stretchy, and comfortable in these summer days. I paired it with a tan linen blazer, and a thin brown belt to show off the bump.
Loved this dress! It’s simple but stylish, and accentuates your curves.
Liked a lot
A very nice dress but there was too much material around the waist area for me (which is usually a problem area). It was not flattering and I did not wear it.
But I didn’t get to wear it out
This dress has a very slinky, fluid quality to it that makes it flattering on the body. The way the fabric drapes and moves creates a smooth silhouette, gently hugging the figure in a way that shapes without clinging too tightly. It mostly conceals small bumps or uneven areas around the midsection it offers a bit of forgiveness while still maintaining a tailored, body-conscious fit. Visually, the overall effect of the dress leans toward a more polished, almost formal look. However, because the material is polyester, it doesn’t feel overly delicate or fussy. Instead, it strikes a versatile balance—you could easily dress it up with heels and accessories for an evening event or wear it more casually with flats or a blazer for a daytime outing or dinner. It’s not showy or flamboyant, which adds to its adaptability. The design is subtly elegant, with enough structure to feel sophisticated but enough give to make it comfortable and wearable across different settings.
Thin silky material. Didn’t find the cut to me flattering
I wore this out for dinner one evening. I'd say it even runs a little large. The cut is flattering, but it's not a very exciting dress.
Not forgiving on anything but a flat tummy.
I wanted work maxi but got chic funeral
The picture is cuter than the dress on the body. There’s little shape and it’s boring. Fine for running errands when I didn’t care but not worth your swap
I thought this would be a versatile item I could wear for date night and the office. It ended up being neither - too matronly for date night, and too formal for the office. I also found it to be quite loose fitting in a way that was not flattering
Dressier than RTR photos show.
