✨ BIG things coming for Tres Co Formal… and we need YOUR input ✨
We are getting ready to do a MAJOR clear-out sale 👏🏼 like… every single dress in the store on sale type of sale because we are bringing in a whole new line and EVERYTHING currently in store has to go 🤭
We’re thinking about opening the formal boutique for a WEEKEND SALE (Saturday + Sunday) so everyone has a chance to come shop, try on, and grab their dream dress for a STEAL 💃🏼
BUT before we lock anything in… we want to know what works best for YOU 🫶🏼
💭 Would you come to a Saturday + Sunday sale?
💭 What days/times work best for you?
💭 Would you want us to do this once… or make it a thing a couple times a month until everything is gone?
We want to make this as convenient (and worth it 👀) as possible for y’all!!
Trust me… you are NOT going to want to miss this. Think:
✨ Homecoming early for a fraction of the price
✨ Mardi Gras / formal gowns for way less
✨ One-of-a-kind dresses you won’t find again
