Zoey was amazing! She picked the perfect blue dress for me on the first time around. She also kept me in the price that I was searching for. She made sure to boost my confidence and help with putting the dresses on and off each time with patience.

Plus size bridal & formal at Mimi's Prom STL

Mimi's Prom STL 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 Mimi's Prom STL

Reviews and the store's own info mention men's big & tall at Mimi's Prom STL — 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.
