Yes. This is the main practical advantage of photo-based try-on over a retailer's own fitting-room feature, which only covers items that retailer stocks.
Save the clearest product image you can find, ideally front-facing on a plain background, and use it as the garment input. A flat-lay product shot or a clean studio photo on a model both work well. Open the image in a new tab to grab the full-resolution version rather than screenshotting a thumbnail, because low-resolution inputs produce blurry, invented patterns.
That freedom is what makes genuine cross-store comparison possible. You can put a jacket from a large retailer and a similar one from a small independent label onto the same photo of yourself and compare them side by side, which no single store's tool will ever let you do.
Some categories are harder than others. Simple solids, t-shirts, hoodies, denim, and knitwear render reliably. Tailored items live or die on the shoulder line, and anything with fine text or an intricate logo is where generation still slips. For those, spend the extra minute on finding a high-resolution product image.
