Perfect, versatile winter dress

Peter Som does it again. It’s so well made and flattering. If you’ve read my recent reviews you’d know that versatility is an important quality for me in a piece and I have been able to wear this to work, to an upscale party and to other more casual social events. Very witchy vibes as well which are a plus ofc

Comfortable and sexy

The fit and fabric of this dress made me feel confident. Doesn’t show sweat and has a sexy neckline. Very comfortable and I loved the slit!

flattering for busties

This was very flattering! As a 44G it's great when a dress can minimize the breasts while also emphasizing them as the star. Super flattering shape & the peep hole wasn't overwhelming for large chested due to the tie. The front tie is very long and easily gets knotted but that's whatever. A good choice for busty babes. Wore to a cocktail party.

Fall party perfection

This wasn’t warm but the colors were perfect for November parties. I paired with suede boots and a suede jacket. The tie at the chest is way too long. It was annoying so I tucked it into the dress. Very comfortable and flattering.

Beautiful and versatile

Wore this for a rehearsal dinner, a work dinner, and a charity event. You could dress it up or down. It fit true to size and had some room to breath. I think this would be flattering on most body shapes.

Loved it!

I’m currently 13 weeks pregnant and have gained about 10 pounds in my first trimester, so the original dress I planned to wear to the wedding no longer fit. As a first-time RTR user, I wasn’t sure what to expect, but the experience was fantastic! I really appreciated having the backup size option, especially since my sizing is a bit unpredictable right now. The size 6 ended up fitting perfectly. For reference, I was 135 lbs pre-pregnancy and am currently around 148 lbs.

STUNNING and perfect for petite!

I’m so in love with this dress. Perfect for a fall wedding I’m attending and fits my petite frame well. I’m wearing it with 3in heels but could also wear flats without it dragging. So flattering and well tailored. The shoulders are slightly loose but it definitely works even for a small chest. Debating purchasing!

Love, love, love this dress!

Such a perfect dress for a fall wedding! Lightweight, flattering and comfortable, and it’s even more gorgeous in person. I received SO many compliments. Fits true to size and I didn’t need a bra, even with a bigger chest! Half tempted to keep it and would 100% rent this one again!

Attractive

Wore to rehearsals in Montana. Switched out with black heels afterwards for dinner. Very flattering. Your bra straps may show on the bottom-sides a little. You can tie the keyhole on the front to whatever size you want. I’m in my 2nd trimester and had no problem wearing this and feeling beautiful.

Great winery dress! Lightweight, flattering, TTS

Loved this dress! Perfect for a 50-60 degree winery day. Light weight, airy, flowy and really flattering. I’m typically a 4-6 and more of a pear shape so I liked that this was fitted through the bodice - yet stretchy! Would rent again!

So many compliments!

Pretty pattern. Super cute, the shoulders just kept sliding down and I had to keep pulling them up all night. I’m quite busty, so I wore a tank underneath as I didn’t want too much cleavage for a work party.

Beautiful but pretty vampy!

Loved this dress but it was pretty autumn/witchy/vampire-y for most occasions. Thats a wild description, but hopefully it makes sense. I wore it once and got a lot of love for it, but it felt almost like cosplay.

Love a flirty long-sleeved dress

Great fit and has elastic for comfort. The tie in front can be open or tight, so there’s some nice options for how sultry you care to look. Wore to work and also out for a concert.

Stunner

Loved this dress even though it was a smidge small in the chest for me. I was still able to wear a bra with it - even with the keyhole opening (the tie hid the very bottom part of my bra). Wore this to a Flamenco show in Spain but it would also be perfect for a date night or party. So flattering. Would definitely rent again.

Not a perfect fit but I made it work and loved it!

I am normally a size 12 but I’m curvy and this dress was very snug around my hips. It also was almost too snug around my bust. I still really liked it so I added a belt and tucked the dress in to make it a little shorter. It was very flattering and good quality. I wore it to a wedding and I got a lot of compliments! 4 stars because I wish it fit my curves a little better!

Good, not great

Overall a nice choice for a fall day at the horse races! A little boobalicious, as other commenters have mentioned, but that I didn't mind. It was snug in the abdomen, so I wore spanx, and the slick material just kept riding up, and the shoulders didn't want to stay up. I happily wore but probably won't rent again.
