Chicago Athletic Association Wedding – Sinead and Marc

Peter Wynn Thompson

Sinead and Marc’s wedding at Chicago Athletic Association was the definition of timeless elegance. Classic, traditional, and effortlessly lovely, their September celebration reflected not only their refined style, but the depth of a relationship built over nearly a decade together.

After their November engagement, Sinead and Marc knew they didn’t want a long engagement. When they found availability at the Chicago Athletic Association for an early fall wedding just ten months later, everything fell into place.  

And what a day it was. Chicago delivered one of those perfect September afternoons — warm but comfortable, with just the faintest hint of fall in the air. 

The morning began with Sinead getting ready alongside her girl squad. Hair was provided by Magnificent Brides and makeup by Sandy Thinnes. Each bridesmaid dressed in soft slate blue gowns in a variety of flattering styles. Sinead’s look was the epitome of classic bridal style: an elegant A-line gown paired with a delicate, pearl-trimmed shawl that added a timeless, heirloom-like touch for the ceremony. Later in the evening, she removed the shawl for a strapless silhouette that carried beautifully into dinner and dancing. Marc and his groomsmen complemented the look perfectly in classic black tuxedos.

Before the ceremony, Sinead and Marc shared a first look on the Grand Staircase — one of the Chicago Athletic Association’s most iconic spaces. Captured by Peter Wynn Thompson, it was a moment filled with anticipation before the celebration began. The couple then ventured out for portraits around Millennium Park, taking full advantage of the beautiful early fall light.

As guests arrived, music from Front of House by Arlen Music Productions set the tone for a ceremony that felt both elevated and deeply personal. The room was filled with loved ones who had witnessed Sinead and Marc’s journey — and the energy was warm and joyful.

Sinead’s bouquet included a meaningful detail: a photo of her father, along with a charm reading “you are always in my heart.” It was a subtle tribute she carried with her down the aisle.

Following the ceremony, guests transitioned into cocktail hour while the ballroom was transformed for the evening ahead. Florals and décor by Stemline Creative embraced a refined, classic aesthetic, perfectly complementing the historic beauty of the Chicago Athletic Association.

Before they joined their guests, Sinead and Marc stepped away together while Sinead’s dress was bustled.  For a few quiet minutes the couple was able to share champagne and hors d’oeuvres while basking in that newlywed glow. It is a simple addition to the timeline that the Five Grain Team always recommends. We learned later that it was one of their favorite memories from the wedding days: a chance to pause, take it all in, and be together before the celebration continued.

Dinner in the White City Ballroom was elegant and seamless, followed by heartfelt toasts that spoke to the couple’s history, their families, and the life they’ve built together. Cutting the beautiful cake from Cake Chicago made for the perfect transition into the next phase of the celebration — the party!
