What is My Size at Flamingo?

By Ella Blake – Fashion Stylist | Tellar Fashion Hub – Always honest, unbiased, & unsponsored post

Flamingo runs true to standard UK sizing across most of its core styles, but there are a few nuances worth knowing before you shop — particularly in their more fitted pieces and occasion-wear ranges, where going up a size can make all the difference between a dress you love and one you never wear again.

I have to be honest with you — I've had my own Flamingo fumbles. I once ordered a midi dress in my usual size and it arrived beautifully cut across the shoulders but noticeably snug around the waist. Classic case of a brand that patterns for a straighter silhouette. Once I went up a size, it was one of my favourite summer buys. So trust me when I say: reading the fit notes properly here is genuinely worth your time.

What is Flamingo's Sizing Like Overall?

Flamingo is a contemporary womenswear brand with a feminine, resort-inspired aesthetic — think floaty midis, bold prints, and occasion-ready silhouettes. Their sizing spans a generous UK 6 to 22 in most ranges, which is a real positive. Here's the general picture:

Standard separates and knitwear — generally true to size, sometimes with a relaxed fit built in, so if you're between sizes, go down.
Fitted dresses and tailored pieces — these can come up smaller, particularly around the waist and bust. Sizing up one is a safe bet if you're on the fuller side of your usual size.
Floaty, tiered or wrap styles — these are far more forgiving. True to size or even size down if you prefer a less voluminous look.
Occasionwear and structured blazers — go true to size for your chest measurement and check whether the waist has any stretch or side seam allowance.

Flamingo Tops & Blouses — What to Know

For tops and blouses, Flamingo tends to be generous through the body but can run slightly narrow in the shoulder and sleeve length, which catches people by surprise. If you carry more width through the upper back, it's worth sizing up and having the waist taken in slightly if needed — or just embracing the more relaxed silhouette, which honestly suits their breezy aesthetic anyway.

Their printed blouses and vacation-style shirts are particularly easy to wear — I'd call these a true-to-size buy with confidence.

Flamingo Dresses — My Honest Take

This is where it gets interesting. Flamingo does stunning dresses — they are genuinely some of the most photographable pieces at their price point. But they do vary by cut:

Slip and cami styles — tend to be quite lean and minimal in stretch, so size up if in doubt.
Wrap dresses — adjustable ties make these genuinely versatile; true to size or up works fine.
Bodycon or fitted midi — always size up. I've never regretted it. The waist seams are often the limiting factor.
Flowy maxi and tiered styles — true to size, sometimes slightly oversized in the bust, which I actually love for hot weather layering.

Flamingo Trousers & Skirts

Trousers and skirts at Flamingo are generally a reliable true-to-size buy, but as with most womenswear brands, the waist-to-hip ratio is designed for a fairly standard drop. If you have a more defined difference between waist and hip measurements, their wide-leg and elasticated-waist styles will serve you far better than anything with a fixed waistband. I'd avoid the structured tailored trousers in this case unless you're planning to alter.

High Street Alternatives When Flamingo Isn't Quite Right

If Flamingo's sizing doesn't land quite right for you, or you're after a similar look at different price points, these are my go-to recommendations:

High Street

Phase Eight — Exceptional for occasion dresses and workwear with proper structure. Known for a generous bust allowance and smart size ranges. A brilliant alternative for Flamingo's more formal styles.
Hobbs — London heritage brand with excellent fit through the waist and a slightly more generous cut than most high street. Great for smart-casual and tailored separates.
Mint Velvet — Very close in aesthetic to Flamingo for everyday wear, with a reliable true-to-size cut. Particularly strong on knitwear and printed blouses.
Anthropologie — For the boho-adjacent shopper, Anthropologie overlaps significantly with Flamingo's resort sensibility. Sizing is consistent and their fit guides are genuinely helpful.
Mango — A slightly leaner, continental cut but outstanding on printed dresses and summer separates. Size up one if you're fuller in the bust.
Me&Em — A more polished, clean-lined alternative. Incredibly well-cut for the waist and runs true to size with a more elevated quality feel.
Coast — For Flamingo's occasionwear range, Coast is the high-street answer. Strong on structured midi dresses and formal pieces, with good size depth.
Whistles — Consistent, true-to-size, and particularly brilliant for anyone who wants Flamingo's elevated look without the occasional fit surprises.

Premium Picks

Reiss — Exceptional mid-range brand with beautiful fabrics and a consistent, flattering cut across dresses, tailoring and occasion pieces. A step up in quality from Flamingo with very dependable sizing.
Sézane — The French-girl alternative. Romantic prints, floaty silhouettes, and a genuine size range. Sézane runs slightly small (I'd always size up), but the quality for the price is hard to beat.

Luxury & Designer

Rixo — If Flamingo had a designer big sister, it would be Rixo. Vintage-inspired prints, exceptional drape, and a cut that's genuinely flattering on multiple body types. An investment buy, but one you'll keep forever.
Zimmermann — The gold standard for resort and occasion dressing with bold prints and thoughtful construction. Sizing runs small (size up and check their detailed measurement guides), but once you get your size right, every piece is wardrobe gold.

Independent Brands Worth Knowing

Ro&Zo — A brilliant independent womenswear brand specialising in flattering silhouettes for sizes 8–24. Their sizing is genuinely inclusive and the quality far exceeds the price point. A hidden gem for Flamingo fans who struggle with narrower fits.
Hera London — A London-born womenswear label with a strong occasionwear edit and bold prints that sit firmly in Flamingo territory. Slightly body-con in approach but sized with generous stretch. Worth bookmarking for wedding guest and event dressing.
