Pricing that's straightforward.

Two numbers sit on most of our pages. The crossed-out one is what the brand charges. The other is ours, set once and left alone. Nothing hides behind either. We call it DY Pure.

Where it comes from

It's less of a pricing method and more of a business philosophy. Strangely enough, I learned it from a woman who sold cars.

Her family ran dealerships in Colorado for decades. When it became time for her to run the business, she thought about what buying a car had felt like for her. The anxiety of not knowing whether she was getting the right deal. The doubt about whether she could hold her own in a negotiation. The hours it took. She wanted to do it differently.

Everyone knows the number on a car's window isn't real. She decided she didn't want to do business that way, and she made the number real. The price on the car was the price. No haggling, no salesman stepping out to talk to a manager. One person looked after you from the first handshake to the keys, and you were out the door.

The philosophy was simple. A business is allowed to make a profit. A customer is allowed to save some money. That is how the relationship with the businesses you spend your money with should be.

Because of this philosophy, I bought six cars from her over the years. It was simple. It took the anxiety out of deciding. And it built a relationship that still rings true all these years later.

It wasn't because of the deal, though the deals were always fair. It was because I never had to wonder whether I had been played. I trusted them. I went back, and I sent everyone I knew.

The business we have built

That's the business we built here. Something you love, priced properly, with retail beside it so you can see what you saved, and a fixed dollar amount from every piece set aside for our philanthropic programs. Numbers you never have to question.

Why we price this way

Retail likes to raise a price so it can mark it down and call it a sale. We'd rather earn your next visit.

That is DY Pure.

Size Guides

Size Guide

Pick a category, find your usual size in the first column, then read across for the same size in other countries. Each table starts with body measurements so you can size from a tape measure. Where a product uses the brand's own scale, the label on that product page takes priority.

How to measure

Use a soft tape over light clothing. Keep it level and snug, not tight. Between sizes? Take the larger for outerwear, the smaller for close-fitting knits and swim.

Measurement How to take it
Chest / Bust Around the fullest part of the chest, tape under the arms and across the shoulder blades
Waist Around the natural waist, the narrowest point above the hip bones
Hips Around the fullest part of the hips and seat, feet together
Inseam From the top of the inner thigh to the ankle bone, standing straight
Foot length Stand on paper, heel to a wall, mark the longest toe; measure heel to mark. Use the longer foot
Head Around the head where a hat sits, about 1 cm (½ in) above the ears and eyebrows
Hand Around the palm at the knuckles, excluding the thumb, dominant hand
Finger Wrap paper around the finger, mark the overlap, measure in mm; or the inside diameter of a ring that fits

Measure feet and fingers at the end of the day, when they are largest.
