FORMAL DRESSES UNDER $150 THAT LOOK EXPENSIVE
Formal season in 2026 is all about looking luxe without spending a fortune. From viral satin gowns and corset silhouettes to sleek strapless styles and statement thigh splits, this year’s trending formal dresses are designed to flatter, sculpt, and stand out. At Thats So Fetch, our bestselling formal collection combines trend-led designs with comfortable fits and premium-feel fabrics like satin, stretchy crepe, and chiffon; perfect for prom, weddings, graduations, and every glam event on your calendar.
What Are the Best Formal Dress Trends Right Now?
If there’s one thing defining 2026 formal fashion, it’s the return of ultra-flattering silhouettes mixed with modern glamour. Corset bodices are everywhere right now, especially styles with lace-up backs, visible boning, and sculpted fits that snatch the waist while still feeling wearable and supportive. Fashion designers and trend forecasts are calling corset and drape dresses one of the biggest trends of the year.
Minimalist satin gowns are also taking over. Inspired by the return of 2000s fashion and “quiet luxury” aesthetics, sleek strapless dresses, spaghetti straps, draped satin, and timeless silhouettes are trending hard across influencer content and celebrity fashion.
Other huge trends for 2026 include:
- Drape one shoulder formal dresses
- Thigh high split gowns
- Gathered and ruched detailing
- Soft draping across the waist and hips
- Bold colors and hardware detailing
- Romantic necklines
- Asymmetrical waistline and contrasting fabrics
At Thats So Fetch, we love designing dresses that feel trend-forward but still timeless enough to wear again for weddings, cocktail events, birthdays, or graduation celebrations.
What Color Formal Dress Is Trending in 2026?
This year’s trending formal colours are all about standing out while still feeling elevated. Across runways, prom edits, and viral formal styling videos, we’re seeing a major shift toward rich jewel tones, soft romantic pastels, and sleek neutrals.
Some of the most searched formal dress colors right now include:
- Cobalt Blue
- Dark Grey
- Midnight navy
- Butter yellow
- Champagne Ivory
- Chocolate brown
- Plum & Purple
- Metallic
- Burgundy
Metallic and deep jewel tones photograph beautifully for prom and wedding content, while soft shades like butter yellow and ivory are dominating formal looks. Satin fabrics especially make these colors pop because of their luxe shine and fluid movement. If you want a timeless look that won’t date in photos, black satin formal dresses, navy gowns, and draped neutral tones are still undefeated.
Long vs Short Formal Dresses: What’s Trending in Australia?
For 2026, long formal dresses are still the biggest trend overall, especially sleek body-hugging gowns with stretch fabrics, corset detailing, and statement splits. Floor-length silhouettes continue dominating prom, weddings, and black-tie events because they instantly create a more expensive and glamorous vibe.
That said, mini formal dresses are making a comeback for afterparties, graduation events, birthdays, and homecoming-inspired looks. We’re seeing more girls pair short dresses with statement heels, messy buns, and glam accessories for that whimsical-inspired aesthetic.
If you want a dress that feels timeless, flattering, and event-ready, a long gown with:
- a thigh split
- draped waist
- corset bodice
- or one shoulder neckline
is still the ultimate It Girl formal look for 2026.
Best Formal Dresses for Curvy Girls
The best formal dress is always the one that makes you feel confident; and that starts with fit and fabric. That’s why stretchy jersey, crepe, satin, and chiffon are such popular choices throughout our collection.
Stretch jersey and crepe is one of our favourite fabrics because it smooths, shapes, and hugs the body comfortably without feeling restrictive. It gives a luxe appeal and creates a sculpted silhouette while still allowing movement, making it perfect for long events.
Satin remains a customer favourite because it instantly looks luxurious while draping beautifully over the body with lots of ease. New-generation satin blends also feel softer, lighter, and more wearable than older stiff satin fabrics.
Chiffon is another go-to for customers wanting softness and movement. It’s lightweight, breathable, and especially flattering for flowy silhouettes, gathered styles, and draping details.
Some of the most flattering formal dress details for curvier silhouettes include:
- Wide straps
- Corset lace-up backs for adjustable support
- Draping across the waist and neckline
- Gathered fabric detailing
- Ruched silhouettes
- A-line or softly fitted skirts
- Stretch fabrics for comfort and flexibility
At Thats So Fetch, we design formal dresses with real body confidence in mind because everyone deserves to feel snatched, supported, and comfortable all night long.
