Suits and coordinated sets are showing up everywhere this wedding season, in shades like powder blue and butter yellow as well as the usual black. A satin set is the easiest version to get right. Destree's light green satin Ruby blazer and Chloé's satin tapered pants pair up in the same pale green, and Farm Rio's floral satin maxi skirt and Amina Muaddi's burgundy patent slingbacks are just as good on their own.

A short jacket with a mini is the playful version of the wedding suit. Sportmax's brown belted Canditi jacket and Agua by Agua Bendita's cream ruffled floral linen mini make an unexpected pair, with Manolo Blahnik's pink tulle BB pumps and Khaite's chartreuse suede Olivia bag adding colour.

Soft colours make tailoring feel right for a daytime ceremony. Ulla Johnson's peach belted cotton blazer over Theory's light blue striped poplin midi skirt and Gabriela Hearst's sky blue ribbed tank is a pastel outfit that still looks polished, and Gianvito Rossi's emerald velvet sandals add one deeper note.

Florals are the traditional wedding guest print, and separates make them easier to rewear. Erdem's black floral crinkled satin midi skirt and Carolina Herrera's red floral cady blouse are both bold enough to carry an outfit alone, with Le Monde Beryl's burgundy Petra mules and Roger Vivier's forest green Vanity clutch.

For an evening wedding, black tailoring is the safe choice that never looks lazy. Saint Laurent's grain de poudre blazer and Liberowe's pleated wool Mika trousers make a sharp suit, Staud's ivory lace-trimmed tank softens it, and Dries Van Noten's embellished gold earrings bring enough sparkle for a reception.

Suits have become one of the most practical things to wear to a wedding, and the fall calendar is a good time to try one. If you take one thing away, let it be that a set is really two pieces you will wear separately for years, so choose each half on its own merits. A satin trouser works with a sweater, and a floral skirt works with a denim jacket. We would skip anything so pale it could be mistaken for the bride's outfit, which rules out head-to-toe ivory and cream. Check the dress code first: a black suit reads right at an evening wedding and a little severe at a garden ceremony.
