Where artistic individuality and luxury collide.

I'm cleaning out my closet(s) and selling live on on May 13 at 12 PM noon.
Download the app and pre-view the sale.
✨️I'm still adding items✨️
last count I was up to 100!!!

What do you expect when its 30 years of my personal clothing, plus some showroom 'one-of-a-kind' samples and a few accessories. There’s one Chanel jacket, a Gucci belt bag, Christian Louboutin shoes, and a Prada skirt. Additionally, I have some pearl and semi-precious accessories from a pop-up I never got to do.

The grand peice is my 1993 French hand loomed raw silk dupioni silk wedding dress with handmade silk roses. The starting price on her is $1k back then I paid $3,000 for the 10 yards of silk. It was made by my uncle's pattern maker Nena. I thought I would use the fabric for a Christening gown but I forgot to have kids 🤦🏻‍♀️ I can DM you photos if interested.

I'll be giving away Proof of Concept 100% luxury pima cotton T-shirts every 10 minutes.

Write in the comments, 'I'm in,' and I’ll send you a $15 coupon. You can share the coupon with friends.

See you today May 13 Wednesday at noon NYC EST. 😘

Lets talk about Zero waste in production.

One of the consequences of working with art, is nailing down the color in printing.
Strike- offs are what the factory sends us for approval so any color correction can be done before it goes into production.

We have taken those strike offs and added some fabric scraps and trims to vintage or deadstock denim jackets.

All the detailing is done by vocational students.
Giving them the opportunity to learn a new skill and get paid.

Massimo supply co. 1997 denim jacket with cotton Jacquard velvet trim.

Ask me any questions before purchasing.

Japanese brands like Whitesville and Tokyo-Tiger are renowned for their circular cotton knit tees, often selling basic white tees for over $100, attracting a cult following. At Proof of Concept, we employ the same vintage cotton knitters, dedicating about 5 days to knit 1,000 yards of Pima cotton. This exclusive technique demands time and cost, offering unmatched weave and comfort compared to generic cut-and-sew tees. Our tees deliver luxury standards and true value, unlike designer tees that charge for the label. Retailers are welcome to try a single tee with no minimum order—just DM us!
