This dress was very comfortable and fit super cute. I almost bought it but didn’t because summer is nearly over here in the Midwest.

Awesome!

Lightweight and perfect for the hot vacay I was on lol. I ended up wearing with nipple pasties and it actually worked fine which is not common for big busties. Obsessed with how my back looked so good too.

My fav dress 10/10

I decided to try something new that I typically wouldn’t wear, and this dress was everything!! The fit was great, and it has plenty of stretch. It was comfortable and light, it was almost 90 degrees when I wore it, but the material was just right for a hot day. So sexy, felt so comfortable, would absolutely rent again.

Comfortable but form fitting. The ties in the back are a little messy but it's a nice elevated casual dress

Loved this dress for a warm winery visit. The fabric is stretchy, with tie string straps that make the neckline adjustable to your liking. Would rent again.

So cute

I would buy this dress. The straps were a little long but I was able to tuck them under the tie and it was fine. Would be better for bigger chested too with a Sticky bra. I really loved this dress

Loved this dress!

This dress was great! The material was so stretchy and comfortable. I got so many compliments on it. Definitely a great/easy summer dress. The back is very open but loved the tie details. I wasn't sure if I was going to love based on the ecom images but it was such a great surprise!

so fun and glamorous

I loved this dress - I wore it on my honeymoon to Sicily and it did not disappoint. Many commented on the unforgiving nature of the middle but I honestly didn't find it unflattering, especially with the right undergarments (I did not wear shapewear and wore Cakes-like bra). I almost purchased this but the number of occasions I could wear this for didn't justify the price. But it's fun! Go for it!

cute and comfy

I wore this to a casual wedding reception and to a rehearsal dinner for a different wedding. I don't usually go for body-con dresses but this one was so fun and cute and skimmed along my body without being tight. The texture of the fabric also helped me feel comfortable because it blurred out any imperfections underneath. You can't wear a bra with this dress, but sticky boobs worked well for me, especially since you can tie the wider straps in the back relatively tight for extra support. Overall I would recommend it!

Supppper stretchy for my 30 week pregnant belly! The fabric is thin so it def shows all the things, but we’re far past caring at this point. Love the color, flounce at bottom, and cute strap details

Loved it - so sad I can't buy it, I want it so bad!!!

Fit well but would buy a size down as the back was a little gapey since my chest is small, was able to make it fit well but it definitely wasn't how it was meant to fit exactly in the back.

Perfect for everyday + bump friendly

Getting dressed for work everyday has been an odyssey at 6mos pregnant but this dress made it so easy! Made of VERY forgiving stretchy fabric while also hugging all the right parts of the waist. Adjustable in the back. Might buy

Beautiful summer dress

Loved this super cute summer dress! It’s really comfy and perfect for hot days. Not the best if you need to wear a bra, but the tie back straps make it easy to adjust for a good fit. Totally a go to for a sunny day brunch

The way the dress moves - chef’s kiss

Yes! The skirt of this dress moves so beautifully. You can feel it swirl around you as you walk and it is absolutely luxurious. I love the color and the fabric. The fabric isn’t “flat” but rather textured - super cool. The straps are adjustable and the bow can help adjust bust fit. It is very flattering, while form fitting not true “body con” or anything. It moves well and is classy. I really liked it if you can’t tell lol. Fits TTS, not bra friendly but could wear pasties. I think the intended look is a bit bare. I love the open back and to style more modestly did an oversized navy belted blazer, was fire. I also styled it with an oversized white jean jacket with brown buttons and I loved that casual look too- it was giving Hamptons. You can tell how well designed it is when you wear it - would rent again! Very cute and I want to try the other Ganni dress in same fabric different cut.

Cute but fits weird

Looked very cute how I styled it but the straps are not adjustable which can cause issues if you have boobs. I am very flat chested so wasn't an issue. Also fabric is comfortable but not forgiving at all it shows any stomach pooch lol

Super customizable fit.

Between the adjustable straps and the tie back this made for a great fit. I’m very short waisted so I have a lot of issues with strap length. Color and pattern were great. 4 stars because the material is not the most forgiving, I couldn’t wear any shapewear due to the low back. Used nip covers, otherwise it would have been a bit naughty.

Comfortable but fabric shows all

Comfy fabric and cute cut but really hard to wear a strapless bra under and have it not show in the back. Fabric is a bit thin and shows unevenness underneath. Doesn’t photograph as well as I thought it would

Cute but thin material

Pictured here with backless/strapless bra - but it didn’t feel like enough. Definitely helped to cinch the back straps and tie. I only wore it for a quick girls meetup and would have worn some shape wear to feel more confident otherwise.
