The Power Suit Dress You Didn’t Know You Needed

Wore this for a big meeting and felt like the boss that I am. It’s the perfect blend of professional and powerful — structured enough to command the room, but still super flattering and comfortable. If you’ve got an interview, presentation or just want to channel main character energy at work, rent this one!

Board room day to night

This was so chic for a big work meeting and the dress has some sparkly thread that gives it a little more upscale and chic look. I sized up for the top and it was a little looser on the bottom so if you are not chesty you could probably size down

Rent this! Professional but fashionable

I loved this blazer dress!! I’m glad I went up a size because it was tight in the chest. The arms were a little big and long, but nothing too crazy. The length was perfectly professional while also being something I could wear for drinks with friends after work

This was such a nice dress. I didn't end up wearing it because it's the material is too thick for May, but I'll rent again for Fall or Winter. Great length for work events which is what I was looking for.

This was the perfect professional dress! Wore it twice for work events and got a million compliments. It's heavy but not too hot. Felt cute but very put together. I wore tights because it was cold but the dress is long enough not to need that.

Phew!

She's a professional stunner. Slight fit issues if you're on the bustier/thicker side. This was difficult to get on and slightly tight in the arms and chest but I made it work. Loved it nonetheless. Consider sizing up.

Workwear superstar

I'm normally a 14 but rented this in a 16 and while i felt comfortable and not sloppy, I think I might try renting in the 14 too (I liked it that much). It's a great warm dress for winter and the silver threading throughout is subtle but adds so much visual interest.

A little too sparkly for work

I felt the buttons with rhinestones made this more formal than I would wear for work. Had they been black, gold, or silver it would have worked. The fit is very nice. It is definitely a cold weather dress. Thick and warm.

Nice cool weather work dress

This dress is beautiful and fits true to size. It was longer than I expected, which actually made it perfect for work. The material is quite thick, so it’s great for cooler weather. The rhinestone-button detail adds a nice touch—though a few were missing on the one I received, it wasn’t very noticeable. The fabric has very little stretch, and between the thicker material and the collared, jacket-style neckline, it can feel a bit stuffy. Overall, though, it’s a chic, polished dress with a structured fit.

Loved this dress. Straight classy, fitting but not overly tight. Hit at a good length for me being 5’2. The navy is sleek and compliments were a plenty. Wore for work meetings into a dinner with a friend at a swank place in the city. I sized up one size and glad I did.

Adorable & Professional Dress

This dress is so much better in person than in pictures! I rented it for a conference. When selecting outfits I asked for some of my friend’s opinions. This was hands down their favorite! Some things to note: It is on the short side, so you may plan to wear tights as I did. It is VERY warm! The material is thick. Conference rooms are always cold so this worked perfectly for me. The inside of the neckline where the lining did not cover was itchy. I didn’t have a tank top or camisole to wear under it. In a pinch I used tissue between the fabric and my skin and it worked wonderfully! (I think it stuck to the texture of the fabric.) The dress has a side zipper that goes from waist to just under the armpit. It was snug around the rib area, so if you are busty consider sizing up. For me this ended up being a great choice based on the quality of the fabric and the cut of the dress.
