IGIGI Review: Plus-Size Designer Dresses in Sizes 12-36

IGIGI Review: this designer plus-size dress label makes IGIGI one of the few brands offering true US sizes 12–36 in bridal, formal, cocktail, and daywear styles — hand-sewn to order rather than scaled up from a sample size.

Who is IGIGI

IGIGI was founded in February 2000 in San Francisco by designer Yuliya Raquel, with a mission to give full-figured women fashion-forward, well-fitting designer clothing. Raquel served as the brand's sole fashion designer and creative director for 13 years, then returned to lead IGIGI again in 2019 through her startup COUTURME, a Y Combinator–backed company, restoring the brand's original focus on sustainable, ethically made plus-size fashion.

That founder-led history matters in an IGIGI Review because it explains the brand's niche focus: rather than adding plus sizes as an afterthought to a straight-size collection, IGIGI was built from day one around the proportions of full-figured women. Roughly 67% of women in the United States wear a size 14 or larger, a demand base that mainstream formalwear retailers have historically underserved.

Sizing and fit

IGIGI's core differentiator is size range. The brand offers designer dresses across US sizes 12–36, which map to EU sizes 40–64, with detailed size charts covering US, UK, and EU measurements alongside bust, waist, and hip dimensions. That range is unusually wide for a designer label — most formalwear brands top out well below a US 36, forcing larger customers into alterations or into skipping designer options entirely.

The fit problem IGIGI addresses is a structural one, not just a numbers-on-a-tag issue. Mass-produced formalwear is typically scaled up proportionally from a standard sample size, which does not account for how plus-size bodies actually vary — the result is often a dress that fits the hips but gapes at the bust, or fits the bust but pulls at the waist. Mainstream boutiques also tend to stock sample sizes no larger than a size 10, leaving plus-size shoppers with little to try on before ordering.

Fit Tip

Check the size chart before ordering

IGIGI's US 12–36 range corresponds to EU 40–64 — measure bust, waist, and hip against the brand's chart rather than ordering by your usual size.

Collection and styles

IGIGI's catalog is organized around occasion, not just silhouette. The collection spans formal evening gowns, bridal and wedding dresses, cocktail wear, and daywear, giving the brand a full lifestyle range from everyday elegance to red-carpet-style formalwear. Named styles referenced in the current catalog include the Vivienne, Giustina, Evangeline, Seraphina, Isadora, Zlata, Roksolana, Celestine, Yolanda, and Ophelia dresses, spanning cocktail-length pieces through full-length gowns. Pairing a formal dress with the right accessories matters too — see our guide to layering delicate jewelry for finishing touches that complement an evening or cocktail look.

Best for entry-level formal

Seraphina Dress

Category: Formal / occasion dress Sizing: US 12–36 (EU 40–64) Construction: Hand-sewn to order

What We Like

• One of the brand's more accessible entry points into its designer formalwear line.
• Full plus-size fit range instead of a capped sample size.

What to Consider

• Made-to-order pieces take 30–40 days to produce, so it needs to be ordered well ahead of an event.

The Seraphina sits toward the accessible end of IGIGI's range and is a reasonable starting point for shoppers who want to try the brand's fit and construction before committing to a full-price gown. Because every piece is made to order rather than pulled from warehouse stock, expect a production window rather than next-day shipping.

Best for statement events

Giustina Gown

Category: Evening gown Sizing: US 12–36 (EU 40–64) Construction: Hand-sewn to order

What We Like

• Positioned at the top of IGIGI's formalwear line for special-occasion impact.
• Custom sizing available beyond the standard range through the made-to-order service.

What to Consider

• Sits at the premium end of the brand's price range as a statement gown.

The Giustina is built for events where a memorable silhouette matters, and it reflects IGIGI's positioning between fast-fashion plus-size basics and full bespoke couture. As with every IGIGI piece, fabric and construction quality come from a hand-sewn, made-to-order process rather than a mass-manufactured line.

Custom made-to-order

Beyond the standard catalog, IGIGI runs a made-to-order program called IGIGI Your Way. Customers can customize classic styles by choosing sleeve length, dress length, neckline, and other details, with the dress then hand-sewn and shipped. Customers who need fully custom sizing beyond the standard size 12+ range can also order custom sizing on made-to-order pieces, with production typically taking 30–40 days for hand-sewn garments.

This model addresses the core fit problem in plus-size formalwear directly: instead of scaling a sample size up, IGIGI builds toward the customer's actual measurements. The trade-off is time — shoppers need to plan around a multi-week production window rather than expecting rush shipping, which matters most for wedding parties and other date-driven events.

IGIGI frames this made-to-order approach as part of a broader sustainability commitment. The brand states that its garments are ethically hand-sewn, with production based in Europe and Mexico, and positions made-to-order manufacturing as a response to fast-fashion waste — noting that ready-to-wear production ranks among the top sources of pollution industry-wide. By producing only what is ordered, the brand aims to minimize excess inventory and material waste.

How IGIGI compares

Plus-size formalwear has historically been a weak spot across the fashion industry, which is part of why a founder-led specialist like IGIGI stands out. Plus-size apparel overall grew 18% in 2021, about three times faster than the broader women's apparel market, and the global plus-size women's clothing market is forecast to keep expanding at a compound annual growth rate of 4.2% through 2033. Within that growth, formal and occasion wear is a particularly active segment as demand for inclusive bridal, cocktail, and event dressing increases.

Positioned this way, IGIGI sits in a middle tier: more expensive than fast-fashion plus-size labels but considerably more accessible than commissioning a bespoke gown, while offering a size range and made-to-order fit process neither alternative typically matches.

Buying guide: what to check before you order

Measure before you pick a size

Because IGIGI's US 12–36 range maps to EU 40–64, don't assume your usual size label carries over. Measure bust, waist, and hip and compare against the brand's published size chart before ordering, especially for a fitted formal or bridal style where alterations after the fact are harder to manage. If you're also shopping for fit-focused pieces beyond formalwear, our guide to choosing a bikini that actually fits covers the same measure-first approach to plus-size sizing.

Plan around production time

Every made-to-order piece is hand-sewn rather than pulled from stock, so build in lead time — particularly for bridal orders or any dress tied to a fixed event date. Ordering close to an event with no buffer is the most common mistake shoppers make with made-to-order formalwear brands generally.

Decide between standard catalog and custom sizing

If a standard size in the 12–36 range fits your proportions, the regular catalog is the simpler path. If you need adjustments beyond that range or want customized sleeve length, dress length, or neckline, the IGIGI Your Way made-to-measure service is built for that — expect the same 30–40 day production window either way.
