Polo Ralph Lauren: SLIM vs CUSTOM SLIM vs CLASSIC FIT — The ultimate guide to fits, sizes & looks
Classic Fit: straight cut, longer, comfortable shoulders.
Custom Slim Fit: intermediate — tailored waist, classic length.
Slim Fit: more tapered and slightly shorter.
Choose according to your chest measurement, desired length (tucked/untucked), and usage (office, weekend, sports).
Understanding Ralph Lauren fits

| Custom Slim Fit | Tailored without molding | Classic | Average builds, versatile use | Smart-casual office, tucked or not |
| Slim Fit | Tapered, slim sleeves | Slightly shorter | Slim/athletic build | Modern look, often tucked |
