The fit guide
Casablanca sizing, season by season.
Casablanca's advice is to take your normal size. It describes its T-shirts, hoodies and swim shorts as a relaxed fit, and labels oversized T-shirts separately. Check the season of a T-shirt: Casablanca updated its T-shirt sizing from spring/summer 2025, and suggests sizing down in newer T-shirts if you want the same fit as an earlier one.

Does Casablanca fit true to size?
On its own product pages, Casablanca describes its printed T-shirts as a relaxed fit and advises taking your normal size. Earlier seasons were described as a unisex fit, with the advice to take your regular size.
Some T-shirts are labelled oversized fit and have a fuller shape. Casablanca's advice for those is still your usual size. On its site, models between 185 and 188 cm tall wear size M in T-shirts, hoodies and swim shorts.
The spring/summer 2025 T-shirt change
Casablanca updated its T-shirt sizing from spring/summer 2025. It still recommends your usual size, but says customers who want the same fit as before should size down. That suggests a newer T-shirt is roomier than an earlier one with the same label.
Our selection includes Casablanca T-shirts from before and after the change. The style code in each product's details includes the season; for example, MS25 marks a spring/summer 2025 piece. If you already own a Casablanca T-shirt, note its season and size, and ask us if you are unsure which sizing applies.
Casablanca's men's size chart
Casablanca uses letter sizes from XS to XXXL, with a chest measurement and international equivalents for each. The chest figures are the same for its relaxed T-shirts, oversized T-shirts and hoodies, so they appear to describe body size rather than the garment. Measure around the fullest part of your chest and compare.
| Size | UK and US | EU | Chest (cm) | Chest (in) |
|---|---|---|---|---|
| XS | 34 | 44 | 88 | 34½ |
| S | 36 | 46 | 92 | 36 |
| M | 38 | 48 | 96 | 38 |
| L | 40 | 50 | 100 | 39½ |
| XL | 42 | 52 | 104 | 41 |
| XXL | 44 | 54 | 108 | 42½ |
| XXXL | 46 | 56 | 112 | 44 |
Hoodies and swim shorts
Casablanca describes its hoodies and zip-up hoodies as a relaxed fit, in cotton loopback jersey with ribbed cuffs and hem. Use the same chest chart. It does not give body or sleeve lengths, so compare those with a hoodie you already own.
The swim shorts are also a relaxed fit, with an elasticated waistband, a drawstring, side pockets and a lining. Casablanca advises your normal size. Its waist figures vary between its charts, so the size you usually wear in shorts is a sensible starting point.
Choosing between two sizes
Casablanca does not publish a rule for choosing between two sizes. Our suggestion: for the intended relaxed shape, choose the size that matches your chest on the chart. If you prefer a neater fit, consider the smaller size, especially in a newer-season or oversized T-shirt.
Lay a favourite T-shirt flat and compare its chest width and length with the piece you want. Our product pages show fit notes where available, and customer care can check a specific piece. You can request a return within 14 days of delivery.
