Great detail

Comfortable pants, great button detail, lots of compliments. They were long enough for me with heals at 5’8. I wore my usual size and fit perfectly

Love love love

If they weren’t over $200 for me to buy, I would’ve just bought them. This is my second month renting these pants. They’re so comfortable, a really nice and thicker material, and I love the buttons down the side. They are super flattering and just a great pair of black pants. I really have nothing negative to say about these pants I’m truly in love.

Very comfy and forgiving

They have a bit of stretch, are high waisted and super comfy. I like that the buttons up until the knee can be opened, gives a bit of flare. Paired with a RTR top too!

This is jusssst a little long wearing a healed boot but makes your legs look a mile long. Wish they had pockets but the look and fit is so good.

Felt long and lean for petite gal

Truth be told, I had to wear some of my higher heels on this one since for this 5’2” baddie these would have dragged otherwise. But ultimately they worked with the right shoe and I felt awesome in them! Loved the button detail that created lots of length!

The buttons on the side here were great, and I loved these pants. They were much too large in the waist for me though. Paired with a Derek Lam shirt from RTR and received so many compliments!

I liked, but didn’t love, these pants. They were comfortable. A bit long so I had to wear heels. Normally a size 00 but they only had a 0 so they ran a bit big for me.

They couldn’t be more perfect!

So fun with the button detail. I happily stepped out of my comfort zone for these pants. Paired with the Ralph Lauren top, and I rocked all day! So comfortable yet polished.

Super cute work alternative

These were really cute and they go with a lot of different tops. Got a lot of compliments on these. They are slightly on the large side, I would say order your usual size or one size down.

Very comfortable and flowy. If you wanted to, you can undo the button from the bottom up to just below the knee for some more flow. But I love the look as is with all the buttons done.

Runs large

Fun pants, lots of compliments. This style runs a full size large relative to the brand’s size chart. Wearable but lower slung on the hips— which helped offset the shorter inseam so I could wear with wedge heel booties. The fabric is heavy and very polyester-y feeling but holds shape well. I’d consider buying if the inseam was 1-2” longer.

Flattering & comfortable pants

These are great for work and easy to style, very flattering fit, and very comfortable. The material is thick but not particularly warm, great for fall or winter. Fun twist on classic black pants. Paired them with an RTR vest.

It’s all about the buttons

These pants are polished yet comfortable. The buttons down the sides are definitely the best part. Plus, they don’t wrinkle. I wore them to the office and dinner with friends. Dress them up or dress them down, the buttons really make the pants.

Too short for 5'9"

I didnt wear these pants. The detail on the side and the material were nice - great quality. Unfortunately, they were not long enough and because of the wide leg, they just made me look huge.

This was a fun pant to rent. Heavy material. Fit true to size. Length was just long enough to wear with a kitten heel or a flat for me at 5'8

The material is warm and drapes over curves perfectly. I think I may buy them…maybe when they go on sale. So far, my best rental.

These are Goldilock pants

These pants are amazing. They fit true to size. They are however, Goldilock pants. You have to be between 5’5” and 5’6.5”, otherwise they’re either too long or too short. Love love love them so much fun.

Fantastic Travel Pants

Comfortable and stylish, I wore these pants twice on air travel days for work trips. They don't wrinkle and looked professional. The only downside is they don't have pockets. At a different price point, I would purchase.

18 weeks pregnant, I sized up for a work event, and the waist and hip width was perfect! The length was slightly too long but I wore a platform shoe to keep them from dragging on the ground. Perfect for New York fall!
