Beautiful dress- fit perfectly!

Size worn: 8
Overall fit: Small
Rented for: Formal Affair
The designer runs very small. I usually wear a size 2 in dresses, but with this dress the 8 fit perfectly. This dress was beautiful! The fabric is much more beautiful in person. I would absolutely recommend this dress. I received compliments all night- especially in sea of black dresses. I also rented the earrings shown on the model with this dress and those matched perfectly.

On-time delivery (last time I rented, it was not!); dress was in perfect condition.

Size worn: 10
Overall fit: True to Size
Rented for: Formal Affair
This dress was perfect! The color was amazing (the dress almost has a sheen to it so it is perfect for spring/summer events). If you have blue eyes, the baby blue details in the dress will really make them pop. I was so sad to send this one back because it was stunning! As a tall girl, I was also very happy that it was the perfect length -- not too long that it makes me feel like an old lady, but not too short so I could still be professional at a work cocktail event.

Perfect for friend's rehearsal dinner

Size worn: 8
Overall fit: Small
Rented for: Other
I wore this to a friend's wedding rehearsal dinner. I had to go straight from work to the dinner, and this dress was perfect for that purpose. I didn't feel out of place at work, but it's fun and bright enough for the rehearsal dinner. I found that it ran small--I usually wear a size 2 but I opted to wear the UK Size 8. The UK Size 6 fit, but was too tight across the hips. Also note that the green is really bright. Like neon bright. I liked that, but just didn't realize how bright it would be.

Great colors, classic style!

I loved this Matthew Williamson dress! It was slightly longer than some of his other styles and the waist seemed to be a little bit tighter. I would recommend going up a size if you feel like your ribcage/bust area can be the reason you go up a size. Great style though and got lots of compliments!

STYLIST REVIEW

Size worn: 8
Overall fit: Small
Rented for: Party
Matthew Williamson runs extremely small as a designer, therefore it was no surprise that I found this style to run on the tighter side. I would size up, even according to the UK size chart. The sizing does not affect how awesome the pattern of this dress is. It gives off a vintage feel which you can really play with. I recommend this if you are looking for something different. There is not stretch in the fabric, especially the chest, so if you are busty I would not steer you towards this style!

Perfect for a springtime wedding!

Size worn: 8
Overall fit: True to Size
Rented for: Wedding
This is such a beautiful dress in person. The color is a very vibrant green, with lilac and grey tomes in the floral print. It was perfect for an early spring wedding, especially one where it is best to err on the conservative side! The fit is pretty true to size, maybe slightly small in the bust, but then slightly large in the waist. I would have preferred that this dress was nipped in at the waist just a little more. The 6 (US size 0) was perfectly nipped in the waist, but the bust was incredibly tight (and I am a 32B!). I ended up wearing the 8 (US size 2), and it was very comfortable sitting, dancing and eating. I received several compliments on the dress throughout the evening. I definitely recommend this for an event where you want to stand out but still look classy and conservative!

I wore this Easter Sunday and was PERFECT!

Overall fit: True to Size

I am always a 0 in dresses and this 0 fit perfect! I am 5' 7 and 110 lbs. I am currently breastfeeding so my bust is currently a 32C and dress was not tight at all in bust. But I have very narrow ribs (ideally I would wear a 27C bra) so that is why it fit in bust. Dress is a gorgeous bright green and material is fantastic. I would highly recommend this dress! I would order it again in a heartbeat!! LOVE it!!

Beautiful color and fabric for spring!

Size worn: 12
Overall fit: Small
Rented for: Other
I wore this to a communion party and it was very appropriate for the occasion. The dress doesn't necessarily for small in all areas but if you have hips or a butt, the pleating is not flattering so I would recommend sizing up. For me, the top half and waist was true to size but the pleating looked stretched out even though the bottom fit. Sizing up looked much better but it was a little bigger than I would have liked over all, however it definitely looked better because the pleats were all flat. The material does not have any stretch but the dress was comfortable to be in all night. Everyone loved the color and design so if you're going to rent, definitely get a backup and size up if you have curves!

A standout color in a classic silhouette

Overall fit: Small

Wore this for an outside wedding. I am very fair skinned with bright red hair and the fluorescent green looked great--I was surprised! Very comfortable to dance in all night. Fit was a bit large but when I went one size down it was too tight and uncomfortable so I opted for the bigger one.

Cute dress - very worn though.

Size worn: 10
Overall fit: True to Size
Rented for: Wedding
I rented this for an early summer outdoor wedding. I have rented a lot of dresses from RTR and this was was the most noticeably worn of any of the dresses I have rented thus far. The dress is very fragile, but there were many pulls and stray threads in the size 10 dress I wore. I am thinking this is why it was so cheap to rent! It is definitely a cute dress, but the wear didn't make it feel as special as the other dresses I have rented.

Stunning, ladylike and unique cocktail dress! Love love love it!!

Size worn: 6
Overall fit: True to Size
Rented for: Wedding
I wore this for my friend's wedding reception in Ft Worth and it was so perfect! I love Matthew Williamson's aesthetic and was so excited to wear one of his dresses! The cut was conservative, but the mix of patterns and shapes made it interesting. I was a little worried about the placement of the gray side panels, but the dress was very flattering on and the colors are vibrant and beautiful..a little brighter than pictured. Even though it's a heavy fabric and it was super hot outside I felt comfortable in it. The fit was perfect, maybe slightly on the snug side, but I think it fit how it should and fell just above the knee on me.

Great modern colors.

Size worn: 6
Overall fit: Small
Rented for: Party
I rented this for my birthday party, which I organized myself: afternoon winery visit, city walking tour, and then dinner out with friends and coworkers. The dress was casual enough to not stand out when the rest of my party was dressed more casually. Great sheen and color in person. I wore the 6 and thought the ribcage was tight by the end of the night, even though I often wear 4 in other dresses. In photos I noticed the bottom half pooched out when sitting down - so sit up straight, ladies! I recently rented another dress from RTW and this one got about 3 compliments while the other got about 100, so it's not the dress of the century. . . but still unusual and stylish.

A perfect dress for a California wedding, super fun colors if you want to make a statement!

Size worn: None
Overall fit: Small
Rented for: Wedding
The fit ran small, so expected a structured/fitted style. Very comfortable, you may want to have 2 sizes shipped in case as the cut is slim. It was a perfect fit on me (size 4), could've worn a 6 if I wanted a looser fit. Coloring is super vibrant and would recommend silver or purple shoes to match. I wore deep purple kitten heels to match the side panels on the dress. I also rented a silver clutch that went perfectly. It was a hit! Highly recommend.

NA

Size worn: None
Overall fit: Large
Rented for: Wedding
The dress ran a bit big.... they didn't have my size left so I went the size up and my husband said when I took it out of the box it looked to big for me. I wasn't crazy about it, for maybe for a summer party it would do the trick. One thing I really didn't like was the green was VERY bright and essentially iridescent. I think it's too late in the year to wear it to a wedding unless it's an outdoor affair.

Fabulous dress

Size worn: 12
Overall fit: Small
Rented for: Wedding
I was worried this dress would look terrible with my very pale skin, but despite the fact that it was a really powerful neon green, it looked awesome. The mixtures of fabrics make it very chic, and the colors just work (though I was definitely one of the brightest at the wedding). The dress is extremely well made and has a very flattering cut. I wore grey/blue shoes which picked up the colors well. I'm between a 4 and a 6 and ended up wearing the 6 (12). I could have gone either way but the 4 was a bit tight on my thighs and I thought it looked better looser with a little movement.

Pretty Dress, unflattering fit.

Size worn: 10
Overall fit: True to Size
Rented for: Wedding
I normally love a sheath dress--my go to style! This dress was beautiful, and the fabric and colors stand out so nicely, but the fit was just a bit off--big in the skirt, tight in the ribs, misshapen in the chest (usually not a problem for me). I wore it to the wedding, but it wasn't something i would normally wear if I was really dressing to impress. I will not rent again.

Wore this dress to a spring wedding and received tons of compliments. The colors are a lot brighter in person and make it stand out. It was a little small in the rib cage so might want to size up.
