Who Are Lounge Underwear?

Launched in 2016, Lounge is a UK-based brand focused on stylish underwear, loungewear, and activewear that empowers women to feel confident and comfortable. Known for:

Bralette sets & balcony bras
High-waisted thongs & seamless briefs
Relaxed loungewear & ribbed bodysuits
Inclusive sizing campaigns

But like many lingerie-first brands, sizing can be confusing—especially with dual size bras, XS–XL bottoms, and the use of stretch fabrics across collections.

So, Does Lounge Run Big or Small?

In short: Lounge generally runs true to size, but select styles can run small—especially in bottoms and structured bras.

Based on verified sizing data and customer feedback:

For Bras:

Triangle bras and bralettes (non-wired): Run true to size with adjustable straps
Balcony bras & push-ups (underwired): Run small in the cup for many users—size up if between sizes
Lounge bras with elasticated bands: Can feel tight on the ribcage

For Bottoms:

Thongs and briefs: Tend to run small, especially in the hip and bum
High-waisted styles: Snug fit—size up for more comfort
Seamless sets: True to size, but compressive

UK Sizing vs Lounge Sizing: What You Should Know

Lounge uses UK standard sizing, but maps its bras as S, M, L, XL, and underwear from XS to XXL. This leads to confusion—especially for those used to numeric bra sizing (e.g., 34C).

Here’s how it typically breaks down:

Tellar Bust Size	Lounge Bralette Size	Bottom Size (UK)	Fit Note
30–32A/B	Small (S)	6–8 (XS/S)	May feel snug in band
32–34C/D	Medium (M)	10 (M)	True to size for most
34DD–36E	Large (L)	12–14 (L)	Bottoms can run tight
36F–38G	XL / XXL (if offered)	16–18 (XL)	Not all sets go up to XXL

Instead of guessing, Tellar.co.uk maps your real bust, waist, and hips to the exact Lounge set that fits your body best.
