Lovely color!

I really like the neckline on this dress! It made it stood out more than an average sheath dress. And the color is so rich! The one downside is it's a bit tricky to get in and out of.

I'm 5'2" same weight so I thought would work for me but it's too small. Size 4 is 14" across at the chest and about 13.2" at the waist.

Very flattering

Love the dress and certainly one I would buy. I wore a strapless bra and it worked perfect. Keeps you walking like a lady due to the pencil bottom. Color and fabric was beautiful. First piece I received with tags still on, loved it!

Cute dress but very disproportionate

I really liked this neckline but really couldn't wait to take this dress off. The body fits fine but the arms and shoulders are VERY tight and rigid if you're more athletic

Beautiful color and neckline

Beautiful dress. Runs small! Snug in bust and hips. No slit in back of dress which means you'll probably want to take elevators instead of stairs and sitting is a challenge. I should have ordered a size up.

Wanted to love it

Dress is beautiful, a little tight on hips but very sexy. Only problem (and I feel like I'm having the same issue with everything in this shipment) was the cute just showed too much breast. I put it on with a single strap bra and just felt like it was not even really on my one shoulder and you could still see the bra strap on the other side. Maybe we smaller breasts or for an evening work event this could work, but for day it was just too low and wide

Great fit, fun color

This dress has nice fabric and great quality. The color is really pretty and different than the sea of black dresses without being too much. I wish I had gotten an 8 (my usual size) as the neckline made it a bit big and difficult to hide a strap. I would wear your usual size.

Day to night

Due to the low neckline, this can only be worn with a strapless bra and should probably be worn with a blazer/sweater at work. Makes for a great transition piece as a cocktail dress for evening though.

Bright blue, interesting neckline

Very hard to zip up on my own, but able to wear without heavy duty underwear. Had to watch posture to avoid bra showing which detracted from feeling stylish with creative neckline. Skirt narrow so impeded walking with full stride & getting in and out of cars. Did get compliments though.

So-so fit and quality

Fabric at top popped out and bit and hard to hide bra straps, barely fit, too snug in arms, would need to go up a size. Felt just okay on quality

Great day to night look.

This is a very flattering dress, which is almost always the case with Black Halo. The color was uplifting and fun. I wore it to a meeting with leadership and to a happy hour after work- very versatile.

The cut of the dress does not work for my body type.

The sleeves are sewn to the main body of the dress in a way that creates an awkward gap at the armpit and if you pull it up the shoulders do not fit properly. Runs small too.

Completely disappointed with this dress. The ordered a 16; I usually wear a 12. The dress fit like a 10. Extremely tight. Bummed and annoyed.

Nice color and cut but absolutely NO STRETCH.

I wanted to love this dress. The color is gorgeous (more of a true purple than it appears in this picture) and I loved the sleeves and the asymmetrical neckline, but it just wasn't comfortable: I felt like I wearing a straightjacket all day. I've never worn a dress for which the warning "no stretch" was more applicable. Perhaps a straighter figure would have less trouble but mine is already pretty straight...

A wonderful color pop for work!

I love this trendy dress by Black Halo! Running true to size with no stretch, I recommend wearing your true size for your primary size and going up for your back up. This style is fitted throughout the midsection and fitted at the hips. It works for all cup sizes. You are able to wear a standard bra, but it may take some adjusting to make sure the straps stay hidden to the side. You may also wear a nubra or strapless bra. At 5’4”, the length hit the knee on me. The color of the dress is amazing in person!My favorite shade of blue!.Pair with nude, black or metallic heels and fun earrings to complete your outfit!

Super cute, I feel like the size runs a little small. To tight for work so I ended up not wearing it. Might try to size up next time.

Beautiful color, fitted dress

I had rented this for a very specific work event. Unfortunately the dress was a bit more fitted then I would have liked for the event. Overall I really did like the dress, definitely runs tighter, it just wasn't the right dress for the day.

Super tight in the shoulders

This felt like it was going to be very uncomfortable so I didn't wear it. I am muscular and busty up top, so this was just wayyyy too tight. The fabric has zero stretch. No thanks!

Beautiful color and cut, no stretch.

Positive: Stunning dress, great color!! Fit hips and waist Negative: Doesn't fit a bust in this size for busty girls. I wouldn't guess over a B cup can wear the size 2.

Power dress

I read the reviews and sized up. The dress fit comfortably and was not too tight. I got some many compliments on the color and the cut of the neckline. I wore it for a very important presentation and I nailed it--partly because I felt so confident wearing this dress!
