Easy to use

Easy to navigate and find the item you are looking for. The app works fast and there are no lags. Looks just like the online website which I love.

This app is JUST as AWFUL as their website. Any filters are lost when you click back from browsing a specific item. Changing colors of a product makes the image of the model unviewable so you can’t see the item in the new color without clicking back, finding the item again, and then clicking back in. No Apple Pay on the mobile app unlike their website. I love theory clothes but their digital shopping experience is almost unusable. Please fix!
