The Design
Look closely and the details hold up: the crest placement, the collar shape, the balance of the Borussia Dortmund Warm Up colors — all true to the 2025-2026 design. From two meters away it is simply a great-looking football shirt, which is the entire point.
Fit & Fabric
A quick note on versions: this is the supporter's cut of the jersey. Same colors, same crest, same name and number as the on-pitch design, with a relaxed fit that makes it wearable seven days a week rather than ninety minutes.
Fan Questions, Answered
+Will this shirt be restocked if my size sells out
Popular sizes and classic designs are restocked regularly, especially retro lines. If your size shows as unavailable, use the contact option — our team can often tell you the restock date before it is publicly listed, and fans on the early list rarely miss out twice
+What is the fit like — slim or relaxed
It is an athletic cut — shaped through the shoulders with a slight taper, but comfortable through the torso. If you prefer a boxier retro look, sizing up once gives you exactly that
+I am between two sizes — which should I pick
Size up. A half-size of extra room is barely noticeable, while a shirt that pulls at the chest gets uncomfortable fast. The chart measurements make the final call easy
+Do you have a size chart in inches and centimeters
The chart above shows both inches and centimeters for every size, so US and EU shoppers can each read the numbers they know. Measure your favorite tee and compare — it takes thirty seconds and removes all doubt
+Is this a good shirt for everyday wear, not just match days
Yes. These shirts have crossed firmly into streetwear, and the lightweight knit is genuinely comfortable for daily wear. Pair it with jeans for a casual look or wear it loud on match day
+How do I remove stains from a football shirt
Cold water and mild detergent handle most match-day stains. For stubborn ones, dab (do not rub) with diluted vinegar before a normal cold wash. Bleach is the enemy of colored football shirts
+Which player and number is printed on this shirt
This shirt carries Guirassy with the number 9 — the name and digits Guirassy wore for Borussia Dortmund Warm Up that season. The lettering style matches the season's typography, so the back looks exactly as it did on the pitch
Ready to wear Guirassy's name on your back? Pick your size from the selector — and if you would rather have your own name and number, custom printing is one option away at checkout.
