Does Rachel Gilbert Clothing Run Big or Small?
Rachel Gilbert garments are true to Australian sizing, which generally runs one size smaller than UK sizing. However, the overall fit also depends on the item:
Category | Fit Notes |
---|---|
Gowns & Formalwear | Fitted bodices and structured cups – designed to shape the body |
Cocktail Dresses | Often body-skimming or draped – hips may be snug if curvier |
Separates & Blazers | Clean tailoring, sometimes cropped – shoulder fit is key |
Bridal Wear | Sculpted and structured – often no stretch, so precision matters |
Tellar.co.uk recommends sizing up if between sizes, especially in fitted gowns.
Otherwise, use your actual bust, waist and hip measurements and let us do the matching for you.

Rachel Gilbert Fit Insights by Garment Type
1. Evening Gowns
These are Rachel Gilbert’s signature, with many styles featuring internal boning, corsetry, or dense embellishment. There’s minimal stretch, especially in structured fabrics like crepe or taffeta.
Fit Insight: These dresses are designed to sculpt and lift — but they don’t accommodate sizing guesswork. Use your exact bust and hip measurements to avoid tightness or gaping. Strapless styles tend to be firmer in the bust.
2. Cocktail Dresses
Mini and midi dresses from Rachel Gilbert range from softly draped to sharply tailored. Popular styles include halternecks, puff sleeves and one-shoulder designs.
Fit Insight: These usually run true to size, but fitted skirts can feel snug if you’re curvy through the hips. Size up for comfort or if you’re between sizes. Shoulder width also matters for asymmetric styles.

3. Blazers & Structured Tops
Rachel Gilbert’s separates are often fitted through the waist and shoulders, designed to be worn close to the body. Cropped jackets, sharp lapels, and strong silhouettes define the line.
Fit Insight: You may want to size up if you have broader shoulders or plan to layer. These garments are cut close and usually don’t contain much stretch.
4. Bridal & Occasion Pieces
Bridal items are often made with delicate hand-finishing and corsetry, so your bust and waist measurements are essential. Many styles are intentionally tight-fitting and require tailoring.
Fit Insight: Brides often find themselves between sizes. Tellar can help identify the best fit for your shape so you can plan for alterations with confidence.
