“I immediately found the perfect dress with that special “wow factor”!”
“Our dress fit like a glove, although they do offer alterations, as needed.”
From the reviews
I went last minute gown shopping because I didn’t feel 100% about the two gown options I previously had for my pageant! I went to KOP mall where I went to the first dress store where two associates did not get out of their seats to assist me! I found my way to Formals XO where I was greeted by Amanda!
We were HOCO shopping, on Saturday, at the plaza. This was my first time in this store and was very impressed. That had a beautiful selection of gowns and dresses. Every color, material and length, you could imagine.
We went in last minute knowing it was by appointment after looking at another store in the mall. We were heavily disappointed in the prior store and didn’t want to waste the trip so we checked out what else was in the mall.
I went into this store looking for a wedding dress and I did, but Ms. Betty got me together. She was kind enough to have me try on a dress and due to it not being the color I needed in the store, she ordered it for me. My dress brought tears to my eyes and made me look as elegant/classy as a bride could be.
Plus size bridal & formal at Formals XO
Formals XO comes up for plus size bridal and formal wear — confirmed on their own site. Two things to know before the trip. First, bridal shopping is usually by appointment — book ahead, and when you call, ask what size range their try-on samples come in. A shop can order almost any gown in your size, but the sample sizes on the floor decide whether you actually get to see yourself in the dress, and the good plus bridal shops stock samples to try, not just to imagine. Second, plan the alterations timeline: gowns and formal dresses typically go through two or three fittings, so the comfortable window is starting your search around 8–10 months before the date and saying yes to a gown by 6.
Big & tall at Formals XO
Reviews and the store's own info mention men's big & tall at Formals XO — extended sizes, longer inseams and sleeve lengths, or a dedicated big & tall selection rather than a single rack. If you need specific sizes (tall lengths, extended necks, wide-width shoes), a quick call ahead saves the trip: stock in the far ends of the size run moves fast, and many stores can order your size even when it's not on the floor that day.
