What Is Sizing Like at Six Stories? Everything You Need to Know Before You Buy

Six Stories is an independent womenswear brand sold exclusively through ASOS, known for its going-out dresses, bodycon styles, and trend-led occasion pieces — and sizing at Six Stories generally runs true to a UK 8–18, though the fit can vary considerably depending on the garment style.

I'll be honest — I first discovered Six Stories about three years ago when I was desperately hunting for something to wear to a friend's birthday dinner. I needed a dress that was a bit more interesting than the usual high street options but wasn't going to cost me designer money. I ordered a size 10 bodycon midi dress, and it fit like a glove. Since then I've become pretty well-acquainted with how their sizing works — and where it can catch you out.

How Does Six Stories Sizing Run Overall?

Six Stories is generally considered to be true to size for a standard UK fit, but there are some important nuances. The brand leans heavily into bodycon silhouettes, cut-out detailing, and stretch fabrics, which means the fit is often quite close to the body. If you're between sizes — say a 10 and a 12 — I'd always recommend sizing up rather than down at Six Stories. You want the dress to sit properly, not strain at the seams on a night out.

Their size range currently runs from a UK 6 to a UK 18, though not every style is available across the full range — worth checking the individual listing before you fall in love with something.

Six Stories Dresses — Sizing Breakdown

This is where Six Stories really shines, and where most of their customers focus. Their dresses tend to be cut in a stretch jersey or bandage-style fabric, and the sizing is generally consistent:

Bodycon midi and mini dresses — True to size, but if you carry more volume in your hips or thighs, go up one size. The stretch is forgiving, but there's a limit. I've made the mistake of sizing down thinking the stretch would sort it — it didn't, and that's an evening I don't want to relive.
Cut-out dresses — Stick to your true size here. The panels are structured and the cut-outs are positioned specifically to flatter, so sizing up can actually throw off the design.
Wrap dresses and tiered styles — These tend to have a little more flexibility. True to size works well, and the adjustable waist means you have some room to play with.
Strapless and bandeau styles — I'd say size up by one if you have a larger bust. The built-in structure can feel restrictive if you're between sizes.

Six Stories Tops and Blouses

Six Stories' tops — corset-style, going-out blouses, cropped styles — tend to run slightly small through the chest and shoulders. If you're a broader-shouldered woman or a fuller cup size, sizing up one is a sensible move. I find their corset tops particularly snug if you're anything above a C cup; beautiful, but worth checking the measurements carefully.

Corset and bralette tops — Size up if you have a larger bust. The boning is not generous.
Satin and mesh blouses — True to size, relaxed through the body.
Cropped going-out tops — True to size for most; size up if you prefer a less cropped fit.

Six Stories Trousers and Jeans

Six Stories doesn't have a huge denim range — they're really a dresses-first brand — but their tailored trousers and occasion-wear bottoms are worth noting. These tend to run true to size on the waist but slim on the leg. If you have fuller thighs or prefer a relaxed leg, size up. The tailored styles in particular have very little give, so don't be tempted to size down thinking you'll "slim into them."

Tips for Getting Your Six Stories Size Right

Always check the size guide on ASOS before ordering — Six Stories does provide a measurement chart and it's more reliable than sizing intuitively.
If you're shopping for a special occasion, order two sizes where possible. ASOS returns are easy and it saves the stress.
The stretch fabrics will ease slightly after wearing, but don't rely on that — if it feels too tight in the fitting room (or in your hallway), it's too tight.
For cut-out and structured styles, measure your waist and hips rather than going off your usual dress size. These pieces are architectural and fit best when they match your measurements closely.

If Six Stories Doesn't Work for Your Shape — Try These Instead

Six Stories is brilliant if you love a sleek, going-out aesthetic — but it's not right for everyone's body or budget. Here are my picks across every tier, chosen for a similar party-ready, occasion-dressing vibe.

High Street Alternatives to Six Stories

Oh Polly — The closest match aesthetically. Bodycon dresses, going-out styles, very similar fit profile. Same advice applies: size up if you're between sizes.
PrettyLittleThing — More size-inclusive and often more affordable, with a similar trend-led going-out aesthetic. Sizing can be inconsistent so use the Tellar Size Lookup before you buy.
Nasty Gal — Great for edgier, more fashion-forward event dressing. Sizing runs small, so go up one.
In The Style — Excellent range of bodycon and occasion dresses, often more size-inclusive than Six Stories, with a similar party-dressing focus.
River Island — More varied silhouettes, reliable sizing, and a solid going-out section. If you find Six Stories too snug, River Island often has a bit more room.
Lipsy — A great shout for occasion dressing, especially if you want a little more structure. Available through ASOS and Next, with a wider size range.
Quiz — Underrated for going-out pieces and party dresses. Sizing tends to run generous, which makes it a good option if Six Stories feels too tight.
Miss Selfridge (ASOS) — The relaunched ASOS-exclusive brand has some gorgeous occasion pieces with a slightly more elevated feel than Six Stories.

Premium Alternatives to Six Stories

If you want to invest a bit more in occasion dressing with better fabrics and finish:

Karen Millen — Excellent for structured occasion dresses with a more sophisticated cut. Sizing is consistent and the quality step-up is noticeable.
Coast — Perfect for weddings, black-tie events, or anything where you want to look polished without going full designer. Sizing tends to be accurate and generous through the hips.
Reiss — More workwear-adjacent but their occasion collection is stunning. True to size and exceptional fabric quality.

Luxury and Designer Alternatives to Six Stories

Retrofête — The ultimate occasion dress brand if money's no object. That sequinned wrap dress everyone seems to own? This is where it comes from. Sizing runs small.
Self-Portrait — Elegant, structured occasionwear that photographs beautifully. A totally different price point to Six Stories but worth knowing about for big moments.

Independent & Niche Brands to Know

Jarlo London — A UK-based independent with a genuinely impressive going-out and occasion dress range. Beautifully made, fair prices, and sizing that tends to be more forgiving than Six Stories through the hips.
Lavish Alice — Another UK independent that occupies the space between high street and premium brilliantly. Their structured going-out dresses are gorgeous and the sizing is more consistent than many comparable brands.

The Bottom Line on Six Stories Sizing

Six Stories is a solid brand for going-out dresses and occasion pieces if you know how it fits. Stick to your true size, size up if you're between sizes, and always check the measurement chart on ASOS before you commit — especially for bodycon and cut-out styles where the fit needs to be precise. The quality is good for the price point, and when a Six Stories dress fits well, it really fits well.
