What Is Sizing Like at Bluebella?

Bluebella runs broadly true to size, but — and this is a meaningful but — it really depends on which part of the range you’re shopping. Bra sizing is relatively straightforward if you know your measurements. Loungewear and soft separates tend to be generous. Bodysuits and structured pieces, however, can come up smaller across the hips and bust, and that’s where most of the confusion (and most of the returns) happens. I’ve been there myself, ordering the Bluebella Emily set in what I thought was my correct size, only to find the bodysuit portion stubbornly refused to accommodate my hips. Lesson learned. Let me save you the same hassle.

A Bit About Bluebella

If you haven’t come across Bluebella yet, where have you been? This is a proudly UK-based lingerie brand that sits in that brilliant sweet spot of genuinely beautiful, directional design without the eye-watering price tag of a luxury house. Think strappy lace bralettes, provocative bodysuits, delicate mesh sets, and some genuinely stunning bridal pieces. It’s the brand you shop when you want something that feels considered and a little daring, whether that’s for yourself or for someone else.

They’ve grown considerably over the past decade, expanding from a small UK label into a global brand stocked everywhere from ASOS to Selfridges. Their size range has also expanded, with their DD+ ‘MORE’ collection bringing fuller-cup options into the fold — which is genuinely exciting for anyone who’s been frustrated by lingerie brands stopping at a D.

Bra Sizing at Bluebella: What You Need to Know

Bluebella uses standard UK bra sizing, so if you already know your bra size, you’re off to a good start. That said, there are a few things worth being aware of before you click ‘add to basket’:

Bands can feel slightly generous — several reviewers (myself included) have found Bluebella bands slightly less firm than expected. If you’re between sizes, sizing down on the band and up on the cup is generally the right call.
Cups vary by style — the half-cup and balconette styles tend to fit shallower breast shapes beautifully, but if you’re fuller or more projected, you may find spillage on the lower cup. Go up a cup size if you’re on the border.
The MORE DD+ range covers band sizes 30–38 and cups DD–G, which is a respectable full-bust offering for a fashion lingerie brand. If you’re a smaller band with a larger cup (28GG territory, say), you may still struggle to find your ideal fit.
Open and provocative styles can fit slightly differently depending on your nipple position and breast shape — Bluebella acknowledge this on their own fit guide, which I appreciate for its honesty.

Clothing Sizing: Loungewear, Bodysuits & Chemises

This is where it gets a little trickier. Bluebella’s clothing-sized pieces — meaning XS through XL rather than bra sizing — are where I’d urge the most caution.

Bodysuits and chemises often come up small across the hips — if you have a fuller hip or are between sizes, go up one. The fabric has some give, but structured pieces don’t stretch generously.
Loungewear and soft separates (their sleep shorts, robes, and cami sets) tend to be more relaxed in fit and are generally true to size or even slightly generous. These I’ve found very wearable for everyday.
High leg and suspender pieces can fit differently depending on your torso length — if you’re longer in the body, be mindful that high-leg cuts may feel uncomfortably elevated.
Slips and long chemises are usually forgiving in fit, but check bust measurements carefully if you’re fuller on top — the seaming doesn’t always have much ease built in.

My honest advice? Measure your bust, waist, and hips before ordering anything structured from Bluebella. It sounds obvious, but I can’t tell you how many of my clients have skipped this step and ended up with something unwearable. A beautiful Bluebella set deserves to actually fit you.

Fit Tips Straight From Experience

Always measure on the outermost bra hooks — Bluebella builds in adjustment room, so you want to start loose and tighten as the garment settles.
For smaller busts, the padded bralette and balconette styles are genuinely flattering — they create beautiful shape without the bulk of a full cup.
For bigger busts (DD+), underwired styles from the MORE range will offer considerably more support than the softer, fashion-forward bralettes in the main line.
If you’re buying a bodysuit as outerwear (very on-trend right now), size up — you want it to skim, not cling to within an inch of its life.
Hand wash. Always. The lace and embellishments on Bluebella pieces are beautiful but not robust enough for a machine cycle. I’ve ruined one too many sets by being lazy about this.

If Bluebella Doesn’t Quite Work for You — Try These Alternatives

Bluebella hits a particular niche: fashion-forward, directional, and mid-price. If the sizing doesn’t suit your shape, or you want something slightly different in style or budget, here’s where I’d send you:

High Street Picks

M&S — The undisputed queen of everyday lingerie. Brilliant fit, wide size range, and their Rosie collection adds a touch of luxury. Consistently brilliant for proper bra fitting.
Next — Underrated for lingerie. Their lace sets have come on enormously in recent years and sizing tends to be very consistent — great if you want reliability.
H&M — For fashion-forward lingerie at a lower price point, H&M is solid. Their satin and lace sets are genuinely stylish for the money.
Calvin Klein — The ultimate for clean, minimal lingerie. If Bluebella’s aesthetic feels a little too much, Calvin’s stripped-back cuts are a brilliant alternative.
Urban Outfitters — Great for bralettes and soft-cup options, especially if you lean towards a more relaxed, undone aesthetic. Sizing is fairly consistent.
New Look — Excellent value, particularly for matching sets. Don’t overlook them — their lace range is much better than you’d expect at the price.
River Island — Strong on satin slip sets and strappy going-out styles. A good Bluebella dupe at a lower price point if you’re after the aesthetic without the spend.
Topshop (via ASOS) — Still one of the best for bodysuits worn as outerwear. The Topshop bodysuit archive on ASOS is genuinely brilliant.

Premium Picks

Anthropologie — Their lingerie and sleepwear is beautifully crafted, with a romantic, feminine edge. Sizing tends to be generous and the quality is a step up from the high street.
Mint Velvet — Known primarily for occasionwear but their silky chemises and soft loungewear are quietly excellent. Great for more grown-up, refined pieces.

Independent & Left-Field Picks

Playful Promises — A brilliant UK indie lingerie brand with a very similar directional, fashion-led aesthetic to Bluebella. They also offer an extended size range and the designs are genuinely distinctive. A brilliant discovery if you haven’t come across them.
Bravissimo — If you’re a fuller cup (D+) and Bluebella’s fit just doesn’t work for you, Bravissimo is the go-to. Everything is designed specifically for bigger busts, and the fit is transformative compared to standard lingerie brands. It’s where I send clients who’ve spent years wearing the wrong size.
