Most people assume you need $500+ to get a special occasion dress that doesn’t look cheap. That assumption is wrong. Both Reformation and House of CB sit in the $200–$300 sweet spot, but they fit completely different bodies and completely different events. If you buy the wrong one for your frame, you’ll spend $280 and still feel underdressed.
I’ve worn both brands to weddings, engagement parties, and one very formal rehearsal dinner. Here’s the honest comparison, including where each brand fails.
Where Each Brand Actually Succeeds (And Fails)
Reformation is a Los Angeles brand built on sustainable fabrics and a very specific aesthetic: slinky, bias-cut, low-back, minimalist. Their dresses photograph beautifully but often feel flimsy in person. House of CB is a London brand built on structure: corset bodices, padded cups, heavy fabrics, serious waist cinching. Their dresses feel like shapewear with a skirt attached.
Neither is objectively better. But for specific body types and specific events, one is clearly the right call.
Reformation: The Bias-Cut Minimalist
Reformation’s core fabric is viscose — specifically their proprietary EcoVero viscose. It drapes close to the body and moves like liquid. The tradeoff: viscose wrinkles if you look at it wrong, and it shows every line underneath. You need seamless underwear or no underwear. Their sizing runs small; I’m typically a size 6 and consistently take a size 8 in Reformation.
Best Reformation dresses under $300 right now:
- Reformation Frankie Silk Dress ($298) — 100% silk, bias cut, adjustable straps. The only Reformation dress I’d call actually well-made.
- Reformation Balia Dress ($248) — square neckline, smocked back, midi length. Good for smaller busts.
- Reformation Juliette Dress ($278) — the viral one. Low back, fitted through the hip. Terrible for anyone above a C cup without tape.
Bottom Line: Reformation works if you have a straighter figure, smaller bust, and want to look effortless rather than structured. Skip it if you need real support or hate wrinkles.
House of CB: The Corset Constructor
House of CB dresses are built like armor. Their signature is the internal corset with steel boning — not plastic — and padded cups that actually lift. The fabrics are thicker: stretch satin, heavy crepe, structured mesh. Their sizing is even more aggressive than Reformation. A size small at House of CB fits like an extra-small anywhere else. Check their size chart every single time.
Best House of CB dresses under $300:
- House of CB Tallulah Dress ($269) — corset bodice, A-line skirt, works for hourglass figures.
- House of CB Carmen Dress ($249) — off-shoulder, internal corset, midi length. Very bridal-adjacent.
- House of CB Lolita Dress ($289) — stretch satin, ruched, designed for curves. The most flattering dress I’ve tried under $300.
Bottom Line: House of CB wins for anyone with curves, anyone who wants waist definition, or anyone who refuses to wear a strapless bra but still wants lift. Skip it if you hate feeling constricted or if you carry weight in your ribcage.
The Fit Comparison Nobody Talks About
Here’s the thing both brands won’t tell you: their sizing models are completely different body types. Reformation designs for a 5’9″ model with a 34″ bust and 25″ waist. House of CB designs for a 5’6″ model with a 36″ bust and 27″ waist. If you’re between sizes, Reformation will gap at the waist and House of CB will crush your ribs.
| Fit Factor | Reformation | House of CB |
|---|---|---|
| Bust support | Minimal. Thin straps, no cups. Requires tape or going braless. | Built-in padded cups and corset boning. No bra needed. |
| Waist cinching | Bias cut skims the body. No compression. | Steel boning corset. Takes 2–3 inches off the waist. |
| Fabric weight | Light viscose and silk. Wrinkles easily. | Heavy crepe and satin. Holds shape all night. |
| Length | Runs long. Designed for 5’8″+. | Runs short. Midi hits above the ankle on 5’7″. |
| Size range | XS–XL, plus limited extended sizes in select styles. | XS–L, some styles to 3XL. Runs two sizes small. |
If you’re under 5’5″, House of CB midi dresses will fit you like a maxi. If you’re over 5’9″, Reformation is one of the few brands that won’t look cropped. This single factor matters more than any style preference.
For Wedding Guests: The Clear Winner
House of CB. No contest.
Here’s why: weddings involve sitting, eating, dancing, and hours of standing. Reformation viscose wrinkles the moment you sit down. After a three-hour ceremony and dinner, you’ll look like you slept in the dress. House of CB’s heavier fabrics resist creasing and the internal corset keeps everything in place even after four glasses of champagne.
The one exception: outdoor summer weddings in hot climates. House of CB’s thick fabrics get sweaty fast. In 85°F heat, Reformation’s thin viscose is actually the better choice — you’ll be cooler, even if you’re wrinkled.
When NOT To Buy Either Brand
If you’re between sizes, have a very long torso, or need a dress within a week, neither brand is your friend. Both run small, both have inconsistent sizing between styles, and Reformation’s shipping takes 5–7 business days while House of CB’s can take up to 10 if you’re outside the UK.
Alternatives worth considering:
- Abercrombie & Fitch Wedding Guest Collection ($120–$180) — surprisingly good satin dresses, true to size, free returns.
- Lulus Everlasting Collection ($80–$150) — budget option, but quality is hit or miss. Read the fabric content before buying.
- Anthropologie BHLDN Sale Section ($200–$300) — the best compromise between Reformation’s softness and House of CB’s structure. Their in-house brand, Wtoo by Watters, is excellent.
If you’re a standard size and have time for returns, Reformation and House of CB are worth it. If you’re on a tight timeline or between sizes, go with Abercrombie or Anthropologie.
Fabric and Care: What You’re Actually Paying For
Reformation’s $248 viscose dress costs them about $30 in materials. You’re paying for the design, the sustainable sourcing, and the brand. House of CB’s $269 corset dress costs them about $45 in materials. You’re paying for the construction — the boning, the cups, the internal structure that takes real labor to sew.
Neither is a rip-off. But understand what you’re buying. Reformation is a fashion purchase. House of CB is an engineering purchase. If you want a dress that holds up for multiple events over multiple years, House of CB’s construction will outlast Reformation’s thin viscose every time.
Care matters too. Reformation dresses are almost all dry clean only, and even dry cleaning can shrink viscose slightly. House of CB dresses are also dry clean only, but the heavier fabrics tolerate more wears between cleanings. I’ve worn my House of CB Lolita dress four times without cleaning it. My Reformation Frankie needed cleaning after one wear because the underarm area showed sweat.
Final Verdict: Pick Based On Your Body, Not Your Aesthetic
Here’s the compressed answer:
- Hourglass figure, want waist definition, need bust support: House of CB. The Lolita Dress ($289) is the single most flattering special occasion dress under $300 I’ve tried.
- Straight figure, smaller bust, want effortless minimalism: Reformation. The Frankie Silk Dress ($298) is the only one I’d recommend at full price.
- Outdoor summer event in heat: Reformation, despite the wrinkles.
- Indoor wedding, long night, lots of dancing: House of CB, no question.
- Between sizes or short timeline: Skip both. Go to Abercrombie’s wedding guest section or Anthropologie BHLDN.
Both brands deliver for the right person. The mistake is buying based on Instagram photos instead of your actual measurements and event conditions. Check the size chart, check the fabric content, check your torso length. Then commit.
