Good Fit

I wore size small. Had a little tiny give but fit good. I wore spandex under. I am 32 waist 37 hips. The straps don’t adjust but they were a good length.

Modern Duchess Vibes in Crochet Elegance

Wore this dreamy blue crochet-knit dress to a Bridgerton-style bridal shower and felt like a modern-day duchess. The fit was flattering, the fabric breathable, and it hugged in all the right places without feeling restrictive. Styled it with vintage green accessories for a pop—and got compliments all day. The length is perfect for petites if you’re pairing with a heel, and the subtle stretch makes it super comfortable for outdoor events. Highly recommend for garden parties, high tea, or any occasion that calls for a little flair. Would rent again? Absolutely. Rating: 10/10 Event: Bridal Shower Size worn: L

Fabric has lots of stretch and was bump friendly. The straps aren’t adjustable so could be an issue if you have a smaller chest size

More of a like than a love

This dress was pretty and worked with the bump since the buttons were not functional. Not something i would rave over but a pretty option. One thing to note is the straps were not adjustable and they were on the tighter side.

I really liked this dress, but the bust was a little odd. Probably should have gone up a size just for the bust, but the rest of the dress fit really well! Color was prettier in person

Body fitting, great color and unique

I rent mostly for work where I need to dress up but can be on my feet moving and lifting for several hours. I paired this with a sheer puffy white top and got many compliments. It is tight and I’m fighting bloat since I can’t get disciplined enough to stop eating things that do me dirty. So it wasn’t the most comfortable, because I am a bit uncomfortable with tightness around d my midsection.

Comfy!

I wore this dress on vacation in a L at 20 weeks pregnant. It was very comfy and cute. I probably could have sized down to M but the bigger size ended up being okay, the straps were just a bit loose since they aren't adjustable. Would rent again!

Comfortable

Could live in this dress. It does run a little big and the straps are not adjustable but other than that it's really so great. It's really comfortable and gets a bit loose as you wear. Will definitely be renting again this summer.

Wore so many times and received tons of compliments

Received lots of compliments, including from folks on the street. I’m small chested so I usually wore a tee under the dress to make up for the fact the front of the dress is a little lower than I’d like. If I bought the dress, which I did seriously consider, I would have the straps shortened to “fix” it. One thing to keep in mind if you are renting in the summer is that it’s a little on the heavier side.
