Wanted to keep!

Loved this hill house. I probably could’ve done a small, it’s snug in the chest, but XS was perfect! Loved this dress, so light and breathable in TX heat. I’m 5’7 and it was the perfect length.

Super cute summer dress

I absolutely loved this dress! It's ideal for summer and can be paired with sneakers, flats, or wedges. The lightweight fabric is of great quality, and I especially appreciated the convenient pockets!

Perfect

Wore this to a golf tournament (August in GA = HOT). Fit perfect, was able to wear a regular bra and the material was so thin I never felt too hot or like the maxi was overwhelming. Would recommend 100x again. Felt cute and also appropriately dressed.

Pretty, tight top

The top part is very tight! Bottom have of the fabric I’m not sure how to describe, thin but stiff. I love the brown color and the pattern and think it’s a great summer or transitional fall piece! Unfortunately because the top was too tight for me, I did not wear. I followed the size guide when selecting but didn’t account for bra/cup size

Cute Dress

I liked wearing this Hill House dress. It was very cute and worked well throughout the day. The arm holes and boob area is a little tight if you have bigger boobs. The length is good for someone 5’4”. I would rent this dress again.

I wear an XS in the Nap Dress and decided to size up to a S for this style. I am busty and it was still quite tight in the chest. Love the print and style though!

Mommy Gut

I’m usually a 2/4 in dress sizes. I went for size XS, it was a little tight on me around the armpit area. I’m pretty fit but I do have a small “shelf” from my c section. This dress pinched me in at the mid section so it exaggerated my gut. I’m 130lbs 5,2 tall. Length was fine. The dress was just an average look.

The Perfect Summer Dress

I wore this to travel during the 4th, to a family BBQ, to work, and to casual dinner with friends. It is so versatile, lightweight, has pockets (huge bonus for when it's too hot to carry a big purse for a little lip gloss or hair tie). I loved this and strongly considered purchasing.

New favorite Hill House style!

I typically always wear a small in HillHouse but found that this particular style was very tight on the bust. The dress was so comfortable otherwise and will rent again in a medium!

Great throw on and go dress!

Loveddd this dress and would have purchased if it was cheaper to buy. Didn't have to worry about ironing it and had pockets, perfect for travel. I wore it with a brown cardigan over my shoulders and Mary Jane's. Loved it, will rent again

Comfy casual

I wore this for fall family photos and it was the perfect casual daytime dress. The brown gingham is really pretty. The bodice runs small, I sized up to a medium because it’s pretty tight. Good length.

Comfortable and flattering!!

I loved this so much I considered purchasing! I was worried it would be too tight in the bust, but it fit perfectly and it provided enough support that I was able to wear it without a bra! For anyone else with a short waist, the cut on this is chefs kiss. Often dresses with a fitted bodice will fall at an awkward spot on my torso but this was incredibly flattering and also such a great transition piece for southern fall weather!

All season dress I didn’t know I needed

This was my first RTR mega win. I wore this dress at least once a week and got so many compliments. I questioned buying it until I wore it for my kids birthday party and questioned why I haven’t purchased it yet. Super easy to wear in most seasons, can’t wait to wear it with boots this fall. Run don’t walk, they hype is real
