Sizing

Each product has its own size guide, which you can access by clicking the “Size Guide” button on the product page. We recommend measuring your own dimensions (e.g. bust, waist, hips) and comparing them with the provided chart to make the most informed decision. Please also read the descriptions as we have added some extra details on certain items.

Please Note:

  • Sizing may vary depending on the brand, style, or fabric. Always refer to the specific size chart for each item.
  • If you’re unsure about sizing or between two sizes, feel free to reach out to our customer support team. We’re happy to help you find the best fit!

BLN SIZING ADVICE

  • If you want a clean fitted look → size down

  • If you want a standard streetwear look → true size

  • If you want it looser or more relaxed → size up


FIND YOUR FIT

House of the Broken Line creates pieces built for discipline, intention, and everyday wear.
Our sizing system is designed to make choosing the right fit simple; no matter where the garment is produced.

All BLN products follow one of our Fit Profiles, so you can choose confidently every time.


BLN STANDARD FIT

A true streetwear fit — comfortable, structured, and clean.
Choose true to size for everyday wear.
Choose one size up if you prefer a more relaxed look.

BLN OVERSIZED FIT

A boxy, drop-shoulder silhouette with deliberate volume.
Choose true to size for a classic oversized feel.
Choose one size down for a cleaner, closer fit.

BLN ATHLETIC FIT (used only on performance pieces)

Slightly closer through the chest and shoulders for active movement.
If you’re between sizes, size up.

Each product on our site clearly states which Fit Profile it uses.

OUR MEASUREMENTS

Every garment is measured flat, in centimetres, to create consistency across all suppliers.
This ensures the size you choose reflects the BLN standard, not factory variations.

You’ll find full measurements on every product page, including:
• Chest width
• Length
• Sleeve length
• Waist
• Inseam (for joggers)

Compare these with a favourite piece you already own for the most accurate result.

MODEL REFERENCES

To help you visualise the fit, each product includes a model reference:

Example:
Model is 5’9” (175cm), wearing size M.
Model is 6’2” (188cm), wearing size L.

This is one of the most accurate ways to choose your ideal size.

SUPPLIER FAQ

Do different suppliers affect sizing?

No. Even though some BLN products are fulfilled through our supplier in the (USA) and some through our European partners, our measurements remain consistent across all suppliers. Every piece is matched to a BLN Fit Profile so you can choose confidently.

Why do some items feel slightly different?

Fabric weight, thickness, and construction can create a different feel — but the measurements remain aligned to BLN’s own standards.

GENERAL ADVICE

If you’re between sizes:
• Prefer a fitted look? Size down.
• Prefer a relaxed or streetwear look? Stay true to size.
• Prefer extra room? Size up.

For oversized fits:
• True to size = intentionally oversized
• Size down = cleaner silhouette
