Very form fitting but in a good way. Paired top with RTR pants and loved the outfit!

Almost bought it. Will prob rent again. Perfect layering top! Great for work and casual wear. As a rental, hard to rewear more than once without dry cleaning because the neck will stretch out from pulling it on and off.

Loved it! Basic but well made, perfect crop length for a 5'8" girl. It's theory though, how could you go wrong?!

Form fighting but flattering. Comfortable to wear all day.

Guys, I can't describe why I love this shirt so much, but I do. The fabric is amazing, it's high quality and makes my body look incredible. I never knew I needed a $230 turtle neck in my life before today.

I wanted a fitted shirt to wear with a skirt and this was perfect. So comfortable and didn't stretch throughout the day.

The fabric was pretty comfortable. The mock neck was a little loose but the rest of the top was very fitted. Didn't love where the sleeves hit me - right in the crevice of my elbow. Perfectly adequate for an average work day, but nothing special.

This top sizes more like a small than a medium on me. It has nice detailing that you may be able to distinguish on my picture. Not my original intention, but this top is perfect if you're looking to show off your top half advantages :-)

Great basic turtleneck. It's pretty thin and fitted, so I think it worked well tucked into a skirt. (The skirt is from RTR Unlimited too!)

I'm 5'6 114lb and the small was too small for me

I love the fit of this top so much I'd rent it again and would consider buying it. It's perfect for a work top that's classic and goes with pants or skirts.

Runs super small...as in when I pulled it off the hanger I thought they'd sent me a kids size. Definitely size up. Otherwise, nice style and nice basic for work.

Runs very small, size up.

Love this mock neck so much I've now rented it twice. The fit is just so lovely. It's fitted but it a great way that feels like it's holding everything in, but not too tight by any means. Great cut on both the neck and sleeves.

Perfect basic for work. Runs small, although I would have sizes down for weekend wear.

Can’t rave about this enough-stays tucked in. Can’t believe I’m buying such an expensive turtleneck top but can’t live w/o it now.

Adorable comfy top! Loved putting this on and it was nice and snug. It does run small though so you could go up a size.

It's form fitting but not tight. Looks great and is very comfortable.

Loved the fit.

Great fit - a little on the tight side. A bit cropped so wear with high-waisted pants if wearing for work!

I own many theory pieces in size 6 or small. This medium was very snug. If you wear theory, go up a size. The medium was very flattering. Goes well with skirts, pants or jeans.

I LOVED this mock turtleneck. It looked great with my pixie hairstyle and small frame. I felt very confident wearing it. It falls shorter on the torso, so it works great with mid-rise or high-rise pants/skirts.

I usually get Smalls for tops, but I'm so glad I followed everyone's lead and got a Large. It looked great on, was soft, and flattering.

fitted and cropped, but not too short

As others said, this is form fitting. Could have sized up twice to the medium. Nice shape and finish, just didn't mix well in my wardrobe.

I wore theory a lot and owns multiple pieces, fitted or relaxed styles, before RTR even exists. I've never encountered a not-true-to-size theory piece as long as it's in PSML sizing category. (True for 00-0-2-4 size 2 or 4 is tricky sometimes). This piece runs small! So small making wearing on and down very unpleasant!!!! This is a solid basic piece suitable for all occasion, texture soft yet structured, good quality as theory always does. BUT IT RUNS SMALL. SIZE UP. MAYBE RTR MADE IT A LITTLE BIT SHRINK AFTER ALL WASHES.

Good material. Flattering. A little short but overall worked great for an interview!

Runs small, the XS was super tight, but it was a rich material

This top was a basic navy turtle neck so there's not much more I can say. I will say while it fit, I definitely could've gone up a size for it to feel less constricting. Heads up (no pun intended) that this is a turtleneck so the head hole is juuust large enough for your head to squeeze up.

I did really love this as a basic, however it needed to be be worn with high waisted jeans and tucked. Worked well over a sweater jacket and a blazer for work. The shade of navy is also much lighter than the photo on the model.

I'm usually a small but this was very fitted and very short. Even with my high waisted pants. I would order again in a medium.

Fits very small and is very short in the torso.

This is short and tight, if you wear a large I think this is going to be too small on you, it is a nice shirt if you are a medium and were to order a large I think
