What Is Sizing Like at Seven Wonders?

Seven Wonders runs largely true to size across its everyday pieces, but the structured styles — corsets, strapless bodices and anything with boning — run noticeably small, so size up if you're between sizes or have a fuller bust. It's an Australian boho-chic label built around floaty maxis, shirred tops and vintage-inspired prints, and it uses Australian sizing (which sits very close to UK sizing, near enough identical for most people). The catch is that the fit swings hard depending on the cut, and that's exactly where people get caught out.

I learned this the slightly embarrassing way. I ordered one of their shirred cami tops and a fitted corset top in the same size, in the same order, feeling smug about it. The cami was perfect — that stretchy, smocked back forgives everything. The corset? I couldn't do the zip up past my ribs. Same brand, same number on the label, two completely different outcomes. So let me save you that particular sulk.

How Seven Wonders Sizing Actually Works

The label designs in Australia for "travellers and dreamers," which translates to breezy cotton, linen blends, rayon and viscose, with relaxed, romantic silhouettes. Here's how the fit breaks down by style:

Shirred and smocked pieces — the most forgiving thing they make. The elasticated panels stretch across a real range, so stick to your usual size.
Relaxed blouses and puff-sleeve shirts — cut with a bit of room through the body. True to size, occasionally slightly generous.
Strapless, corset and boned bodices — these run small and have little to no give. Size up if you're in between, and definitely size up if you're a C-cup or above.
Lined slip and wrap dresses — usually true to size but rarely stretchy, so there's no wiggle room. If you carry weight on your hips, check the hip measurement before the bust.

My non-negotiable rule with this brand: read the "fit info" tab on the individual product before you buy. Seven Wonders is genuinely good at flagging when a piece runs small — they'll tell you to size up — and ignoring that note is how the returns pile starts.

A Stylist's Tip on Measuring

Because the fit is so style-dependent, your dress size is almost useless here on its own. What matters is your actual bust, waist and hip measurements in centimetres, matched against the specific garment. The strapless styles in particular live and die by your bust measurement, not your "usual" size. Measure once, properly, and you'll buy with far more confidence — more on the easy way to do that below.

Where Else to Shop the Seven Wonders Look

If a piece is sold out, out of your budget, or you simply want the breezy boho aesthetic with a fit that suits you better, here's where I'd send clients across every price point.

High street:

Mango — consistently nails the holiday-dress brief with broderie, linen and floaty maxis at a sensible price. My first stop for the look.
Anthropologie — the closest spiritual match on the high street: romantic prints, occasion-worthy detail and beautiful fabrics.
Monsoon — long-standing home of embellished, floaty occasion dresses, brilliant for weddings and warm-weather events.
Boden — playful prints and easy summer shapes with a reliable, generous fit that suits a fuller figure.
Phase Eight — grown-up occasion dressing; their midi and maxi styles photograph beautifully.
Coast — go-to for structured strapless and bodice-detail dresses if Seven Wonders' version runs too snug.
Hush — easy, throw-on boho separates and slip dresses in lovely soft fabrics.
Whistles — elevated prints and clean silhouettes when you want the breezy look slightly more polished.

Premium:

Sézane — the French answer to romantic dressing: puff sleeves, delicate prints and proper fabric quality that lasts seasons.
Ganni — for the bolder, print-led side of boho, with a playful Scandi edge and a more directional cut.

Luxury / designer:

Ralph Lauren — the original prairie-meets-vintage romance; the tiered and floral dresses are forever pieces.
By Malene Birger — elevated bohemian with gorgeous prints and a more sculptural, grown-up silhouette.

And two left-field independents worth knowing:

Faithfull the Brand — Bali-made, vintage-inspired and almost a sister label to Seven Wonders in feel, with a slightly more refined finish.
Kivari — a small Australian boho label doing hand-detailed, free-spirited pieces that feel genuinely special rather than mass-produced.
