The FLATstrap is a chest-minimizing shapewear undergarment made for comfort and self-expression. On Sunday, November 15, we're launching it with a four-hour party at The Rotunda.

Come get fitted for powerful pecs, meet the people who helped shape it, watch a great lineup of performers, and take a deep belly breath in a room full of people who are glad you're here.

The party is also a fundraiser for our Share It Forward Model, an affordability program that will offer free units to queer and trans people who can't afford the current price. Every ticket helps.

What's happening

Get fitted. Private spaces will be set up for fittings, so you can try the FLATstrap on at your own pace. A rack of styles will be on hand so you can see how it sits under shirts, jackets, and whatever else you want to wear over it.
Get your photo taken. The photo booth is the place to try the FLATstrap on and strike a pose, if you want a picture of the moment. Sharing is always your choice, and we only post photos of people who say yes. Nobody takes photos in the fitting spaces.
Make a packer. Darb Garb is running a crafting station where you can learn to make your own whimsical packer.
Watch the show. Edith Poussard hosts an afternoon of live performance, with sets of 5 to 10 minutes so something new is always starting. Naija Couture/Adonis is on the decks playing jams all afternoon.
Eat something. Catered bagels and fixings will be out all afternoon.
Reserve yours. If you like how it feels, you can pre-order a FLATstrap at flatstrap.euphorm.co. Pre-orders are guaranteed to be fulfilled before the end of 2026.

Lineup

Host: Edith Poussard

How tickets work

Tickets are pay what you can, on a sliding scale from $0 to $50. Nobody is turned away for lack of funds. If you can pay more, you're helping cover the guests who can pay less. If money is tight, choose $0 and come anyway.

To help you decide, here's how we think about the common levels: $15 if you can pitch in a little, $30 if you want to cover your own seat, and $50 if you'd like to help cover someone else's.

Everything raised goes to our Share It Forward Model, which helps close the affordability gap by offering free units to queer and trans people who can't afford the current price.

Walk-ups are always welcome.
