Trapezoid body shape with cool, light skin tones (Light Summer)

The one thing to buy

Slim-fit shirts in white. The cut comes from the trapezoid rules, which put a slim-fit shirt +7.3 ahead of a neutral garment; the colour comes from the Light Summer palette, where white sits ΔE 2.4 from #F2F1EE. By the usual convention: a balanced build is best served by cuts that follow it rather than reshape it.

The colour matters here more than it usually would. A slim-fit shirt is worn near the face, so it is one of the pieces where a palette miss reads as tiredness rather than as a colour you happen to be wearing. White sits ΔE 2.4 from #F2F1EE in the Light Summer palette.

What to buy, and in what colour

A clean shoulder, a marked waist, and a clean leg line. That sentence is the shape half of the answer; the colour beside each garment is the other half. They are not applied evenly: 3 of the 3 garments the rules want for a trapezoid are worn near the face, where a Light Summer palette miss shows on the person, and the rest sit below the waist where it shows only on the garment.

• Slim-fit shirts (+7.3), near the face: in white, ΔE 2.4 from #F2F1EE. A balanced build is best served by cuts that follow it rather than reshape it.
• Structured blazers (+7.3), near the face: in white, ΔE 2.4 from #F2F1EE. A balanced build is best served by cuts that follow it rather than reshape it.
• Unstructured blazers (+7.3), near the face: in white, ΔE 2.4 from #F2F1EE. A balanced build is best served by cuts that follow it rather than reshape it.
• Boxy jackets (-5.3): the cut is the problem on a trapezoid, and no Light Summer colour rescues it. Boxy volume hides the natural taper that is this frame’s main asset.
• Oversized shirts (-5.3): the cut is the problem on a trapezoid, and no Light Summer colour rescues it. Boxy volume hides the natural taper that is this frame’s main asset.

The Light Summer colours worth building on

Cool and light. Gentle, watery colours; contrast stays low. 4 of the twenty-four colours an ordinary shop names land inside the palette, and Burgundy is the furthest out at ΔE 42.4. For a trapezoid these are the colours to find the 3 near-face pieces above in; white is the neutral to build the rest of the wardrobe from.

• White (#FAFAFA): ΔE 2.4 from #F2F1EE.
• Blush pink (#E8BFC4): ΔE 2.7 from #E8C0CC.
• Grey (#9A9A9A): ΔE 4.7 from #8E9299.
• Sky blue (#8FC1E3): ΔE 5.0 from #A8C4DC.

Where the two disagree

They can, and the order matters when they do. Shape is geometry: a cut that adds width at the widest point does it whatever colour it is. Colour is a claim about a face at a distance, and it only binds on the pieces worn near one.

On this pairing it arises 3 times. A slim-fit shirt, a structured blazer and an unstructured blazer are worn near the face, so the palette binds there in a way it does not across the rest of what a trapezoid should be buying. Hold out for it: Light Summer gives you 4 colours that clear the bar, which is enough to find the cut you want in one of them.
