Beautiful dress!

This dress hit me at the ankle for a short girl. I didn't mind, just an FYI for tall girlies. I didn't like how the ruffles made my shoulders look wide so I just rolled the sleeve up and it was much more flattering. Still loved it!

Flawless

This dress is perfect in every way! The fabric is absolutely gorgeous and the ruffles and low back provide just the right amount of charm and drama. I don’t think any dress has ever fit so perfectly. The one con was that I couldn’t wear a bra and needed to use some tape, which was a bit tricky. I imagine this wouldn’t be an issue for less busty ladies!

Gorgeous and High-Quality, Just Not the Easiest Wear

Wore this to a formal wedding. The print is beautiful and the fabric feels high-quality—it drapes really nicely and the fluttery layers are cute. But it’s definitely not the most practical. It’s completely backless (I wore nipple covers), the fabric is sheer—especially in daylight or with flash—so you’ll need a slip, and the armholes are quite large, which is something to consider. Overall, a striking piece, but it takes some prep to wear confidently and comfortably.

Lovely and flowy dress!

This dress was great for a wine tasting and auction fundraiser. I carry most of my weight from the waist down so I tied it in the front to distract from any belly bulge. It didn’t show the unflattering edges of my back. I did think the arm hole was a bit large and should have been posing with my arms down. The L would have been too large on top for me.

Lovely romantic dress

This dress flows in all the right directions. I was worried about sizing because my hips are wider but the fit was generous while not being baggy. Felt comfortable and classy all night. Wore it with gold jewelry and heels but I think it has the potential to be dressed down as a summer dress with some black sandals.

Beautiful Dress

Wore to an award ceremony for work, perfect for the occasion! The address is lightweight and easy to wear. The dress has an open back, did need to use tape to secure on the front side. The girls dress was a perfect length for my height in heels.

Beautiful Dress!

When you go to rent this, jump on Amazon and order your low-back shape wear at the same time. The fabric is forgiving, but it is a little thin. You'll want something under it. If you are doing more than a photo shoot, get some small safety pins and fasten the straps to your shape wear.

Flowy yet sultry

The material was light and airy and the pattern was super pretty. The low-cut back gave it a boost of sexiness despite the fact that it was floor-length. Good for dinner, vacay, cocktail event. Could def be worn dressed up or down!

A memorable dress

If you have curves, you’re going to love the fit of this dress. It’s simply gorgeous. The colors are vibrant, the material is beautiful, it hangs beautifully and swishes perfectly. It’s so very feminine and elegant. Mine came missing the belt, however it didn’t make any difference. Usually this brand can run smaller, this dress I could have sized down. Normally I would have taken a lg however this was on my watch list and it came up and I nabbed it. Rent it.

Gorgeous dress

If you have a chest that needs support, wear low back shapewear with a strapless bra. I completely forgot to pack sticky boobs and had to wear a strapless bra that I pulled way down in the back. Regardless, sticky boobs wouldn't have been enough either because the fabric is very delicate and sheer. Gorgeous dress outside of my own mistake. Fit like a dream and got lots of compliments.

I’m between a 6-8 and usually fall more towards an 8. I rented the medium and wished all night I had the small. The hip, back, shoulders, and arm pit areas were all huge. Gorgeous dress and very flattering just size down.

Cha cha cha

I'm 5'3" and the regular length was totally fine! Just dusting the ground in 3" heels. If you want to wear a bra it needs to be sticky, but I went without. Didn't feel needed. Super cute, a bit thin, but had great flow .

Beautiful Dress

I definitely recommend this dress. Very flattering and comfortable. I thought there was no way I could fit into the dress when I opened it, but the small fit perfectly. The back makes the dress. It is kinda see through but was fine with a slip. Rent this dress!

Beautiful spring wedding dress!

Great dress for a spring wedding. I’m usually a 4/6 and both the XS & S fit, but I liked the way the S fit better. High neck/low back but very flowy, feminine dress!

Lovely dress that hugged the right spots

Loved how lightweight this dress was, and had great movement. The back was too low for a traditional bra, so I used sticky nipple covers. The material is slightly sheer, but since it is double layered, undergarments (or lack) isn’t detectable.

Loved this print!

Reminded me of little strawberries (I know they were supposed to be roses) but fun print for a spring wedding. The dress fit true to size (no stretch) but there is a belt that can help tighten the back giving you more of an hourglass look. The ruffle hit at the perfect spot. It's open back so you can't wear a bra!

great spring/summer wedding guest dress!

tons of compliments - slightly lower back with a ruffle - flattering fit on me (although my adult petite size daughter tried on and she felt a bit matronly) - felt a bit big/wide at shoulders at first, but sleeves stayed up all night without any issue.

Cool back but thin and see-thru

The front wasn't a standout and the material was sheer with only 2 layers and no lining. I couldn't wear a bra because of the low back (which was beautiful) but with the thin material no bra wasn't going to work.

Such a pretty dress from the front, but needs serious strap reinforcements for back

This is such a pretty print and flattering dress from the front but idk how people wore this without using a pin for the back. The sleeves fell down constantly and would expose your side boob if you didn’t pin them. I ended up pinning the upper back entirely to keep the sleeves up, which took away from the open back design.

Runs Large, Awkward Ruffles

The dress print itself was really pretty for a spring time wedding, and the open back was really cute, but the ruffles on the neck were not flattering. The arm holes are also large which made wearing boob tape a little challenging and visible.

Lightweight but elegant

The fabric on this dress is incredible! The two layers of the fabric help to make it opaque but it is light and comfortable. I rented in a shipment to try for a later formal affair, and I'm glad I did because my usual size of 12/XL was too big, so would recommend sizing down just one size.
