Relco London’s Two-Tone Tonic Trousers take inspiration from classic 1960s British tailoring and the smart-casual mod and ska look that followed. The cut is slim with a gentle taper, finished with two button-down back pockets, angled side pockets, and a clean waistband with belt loops and inner grip to keep everything in place. The Polyester/Viscose blend gives the cloth a slight sheen and that familiar “tonic” colour shift — a deep blue that catches hints of lighter tones as the fabric moves.

The trousers sit neatly on the waist with an 8-inch hem and a two-inch inner turn-up, giving you the option of a cropped, period-correct finish or a standard length.

The rich two-tone weave makes these trousers surprisingly versatile. Pair them with a Gabicci knit polo in cream, white, or mustard for a classic soul-night combination. For a more casual look, a 66 Clothing in off-white, grey, or burgundy sits perfectly against the blue. On the feet, Modshoes loafers or desert boots in tan, oxblood, or navy complement the tone and finish the look without overdoing it.

Add a Harrington or tonic-weave jacket when layering — the contrast of textures gives a subtle nod to vintage styling without feeling dated.

Relco’s Two-Tone Tonic Trousers are built on solid tailoring and sharp detail — ideal for anyone who appreciates clean lines, good fabric, and understated colour.
