    Button-Up Sizing Guide

    Fit is incredibly personal - some like their shirts to fit snugly around their body while others prefer to wear them looser. We've provided a number of fit charts below to help you find your fit. Note that there are some variations in the way different fabrics will hang on your body, and some shirts will fit more snugly than others. We recommend always sizing up in flannel.

    NEW - we've added a bust-waist-hip circumference measurement chart below. If you're at the top 1 - 1.5 inches of the bust range, you will likely have to release the box pleat.

    Bust, Waist, Hip Measurement Size Chart

    Below are the flatlay measurement charts for our Alpha shirts. We have shown our measurements taken from lying the garment flat and measuring in inches. We recommend grabbing a shirt you own in similar fabric and comparing!

    In between sizes? Go for the smaller one - there’s a pleat in the back of every PDL shirt that you can remove with a seam ripper - this will give an extra 1½ inches to prevent button-gape.

    Note about sizes 18 and 20: We have released our NEW 18 and 20. When purchasing these sizes, please check the item description for whether they are "new" or "old" sizes.

    If you were a size 20 in the old sizes, you are likely a size 18 in the new sizes. If you found the old 20 too small, give the new 20 a try!


    All PDL Alpha fit shirts have the following features: 




    Customizing Your Shirt with the Box Pleat

    The box pleat at the back of every PDL shirt allows for a bit of flexibility in sizing.

    Removing the Pleat for More Space in the Bust

    If your shirt fits in the shoulders and arms but is a little snug through the bust, you can remove the pleat to gain an extra inch and a half in that area. Kindly note that shirts with the pleat removed are no longer eligible for exchange or refund.

    To remove the pleat, you will need a seam ripper. This little tool comes with most sewing machines and sewing kits. Watch the video below to see how it's done:

    Extending the Pleat to Take Your Shirt In at the Hips

    If the shirt is too roomy around the hips, you can also extend the pleat to take the shirt in by 1 - 1.5inches from the waist down. This is a pretty simple sewing job if you have the skills. You'll need a sewing machine and an iron. Kindly note that all modified shirts are ineligible for return/exchange.

    Spread Collar Holiday/Camp Shirt Sizing

    This size chart applies to our "camp collar" shirts. Kindly note that these shirts have no pleat! There's a bit of extra space in the bust and hips compared to our regular Alpha fit shirts. These were designed to be worn open, but you can button 'em up too.




    Alpha Jacket Sizing

    Here's a rough translation chart between our button-up shirt sizes and our wondrous, pocketed, Alpha Jackets. Please note that a match on these charts will mean that the button-up and the jacket will be the same size; go up a size if you'd like a looser fit!
