How To Measure Yourself
Use a soft measuring tape to wrap around yourself and find your perfect Girlfriend fit!
1. Bust: Measure at the fullest part of your bust wearing a non-padded and non-compressive bra (or no bra) with arms down and relaxed to your sides. Measuring tape should be relaxed at your bust.
2. Waist: Measure your natural waist, i.e. the smallest part of your waist, usually where your torso bends.
3. Hips: Measure the fullest part of your bum wearing non-bulky bottoms.
4. Inseam: Standing straight up, measure from the center of your crotch straight down to your ankle bone. (If someone finds a better word for crotch, let us know.)

FAQs
Are your garments true to size? Yes, we aim for everything to fit true to your normal size, but there are always slight variations between brands. We recommend referencing our sizing chart to find your perfect fit.
What if I'm between sizes? If you're between sizes, we suggest sizing down for a more compressive fit and sizing up for a more relaxed fit.
I have a long torso, should I size up in unitards and dresses? Generally, we recommend taking the size you'd get in tops for unitards and dresses. If you have a longer torso and want a more flexible (less compressive0 fit, we recommend sizing up!

The cobalt blue is beautiful. It is a bit short - I’m 5’8” and 135 lbs and I got a medium. Also if you don’t push the shorts up, you can see bottoms of them them under the dress.

Absolutely love this dress, it is so flattering and comfortable! I love that I don’t have to wear a bra and the shorts stay in place keeping my thighs from chafing. I’ve been wearing this non-stop and I’m definitely getting other colors!
Was this helpful? - VVickyReviewingGumdrop Ava Long Sleeve Mini DressBust Size A-B cupSize Purchased MRated 3 out of 5 stars7 months agoSuper cute but doesn't fit right
This is so cute and I didn't know it was going to be ribbed fabric, but I don't mind. Ultimately decided to return it because it didn't fit well. I'm 5'5 and 140lbs and have more of a rectangle body shape. There was a bit of extra fabric that bunches up on my lower back above my butt. The built-in shorts are pretty tight and rise up a bit, making it pretty uncomfortable. I did appreciate how stretchy it was while sucking almost everything in. However, if you buy it in a light color, it won't be as forgiving. I did love the color - it's a perfect pastel pink that isn't too vibrant or washed out.

- LBLeila B.ReviewingBlack Ava Long Sleeve Mini DressI recommend this productBust Size C-D cupSize Purchased LRated 4 out of 5 stars8 months agoNice but very short
I like it! I wish the skirt was a little longer than the shorts underneath. But it’s comfortable and the fabric is nice and sturdy and I like the texture. I’ve been wearing it with opaque black tights because I don’t want the shorts to show and I feel like the skirt is always threatening to rise up. Mostly happy with this but it’s not perfect.
