Lena Dunham appeared significantly slimmer while attending Taylor Swift's recent wedding festivities. The "Girls" creator, 40, was present at both an intimate rehearsal dinner and the larger ceremony and reception held at Madison Square Garden.

Dunham's stylist, Talia Cassel, shared photos on Instagram revealing two custom outfits worn by Dunham. One ensemble, a lime green skirt suit by Amber Doyle, featured a knee-length skirt and matching shoes. The other, a creation by Christian Cowan, included a magenta top with flared cuffs and a large tulle floral brooch, paired with a floor-length black skirt designed to cinch the waist.

Dunham, a close friend of Swift, also delivered a speech at the rehearsal dinner that reportedly left some guests in shock. The ceremony itself saw Swift exchange vows with NFL star Travis Kelce, with notable attendees including Brad Pitt, Jennifer Lopez, and Beyoncé.

Dunham's fluctuating weight has previously drawn public attention. Last year, she commented on the body positivity movement, stating that while she doesn't criticize individual choices regarding weight loss methods like Ozempic, aesthetic reasons often influence body desires. She has previously attributed her weight gain in recent years to sobriety and medical issues, including endometriosis and early menopause following a hysterectomy in 2017. In 2019, she expressed happiness with her heaviest weight, embracing a more relaxed approach to her body.

The wedding also presented a potential awkward encounter for Dunham, as her ex-partner Jack Antonoff, a frequent collaborator of Swift's, was in attendance. This potential discomfort may have been heightened by Dunham's recent memoir, "Famesick," which offers a critical account of their past relationship.
