Lycra (also known as elastane or spandex) delivers stretch, comfort, and shape retention—ideal for bodycon dresses, activewear, swimwear, and more. But sizing is crucial: since lycra fits snugly, over-sizing can lead to slipping or sagging. In fact, advising against sizing up unless fabric has very low elastane, Tellar recommends staying true-to-measure or sizing down for the sleekest silhouette themes.shopify.com+13tellar.co.uk+13tellar.co.uk+13.

Here’s a breakdown of the best places to buy lycra pieces:

🛍 High Street

• Zara, H&M, Mango, ASOS
    These mainstream retailers offer stretch-rich basics—skinny jeans, yoga leggings, bodycon dresses. However, sizing varies widely. Brands like Zara frequently run small, while H&M may fit true-to-size tellar.co.uktellar.co.uk+1tellar.co.uk+1.

• Nike, Adidas, Gymshark
    Their activewear lines with high elastane offer compression and support. Stick with your normal size to maintain performance.

👗 Designer Labels

• Reiss, COS, & Other Stories, Massimo Dutti
    Often incorporate 1–5% elastane in trousers, dresses, and skirts for sleek fits. Mid-range designers typically deliver well-tailored stretch pieces—yet cuts differ, so fit checking is essential.

• Conner Ives, high‑end streetwear
    Using upcycled jerseys and patchwork, sizes can swing dramatically—even within the same collection. Tellar confirms that relying on sizing without tailored tools is risky tellar.co.uk+5tellar.co.uk+5lomfashion.co.uk+5tellar.co.uk+7tellar.co.uk+7tellar.co.uk+7tellar.co.uk+10tellar.co.uk+10tellar.co.uk+10.

🛒 Boutique / Independent Brands

• L•O•M (Louise O’Mahony)
    Their luxury printed lycra pieces are intentionally snug—if you’re between sizes, they suggest sizing down lomfashion.co.uk.

• Other niche labels
    Often lack standardized charts. Email measurements for bespoke advice—Tellar can assist after measuring or comparing to a known brand.
