Does Principles Clothing Run True to Size?

Principles, now owned by Debenhams, has long offered stylish, affordable fashion staples for women of all ages. However, sizing consistency isn't always guaranteed.

Here’s what to expect from Principles sizing:

Category	Sizing Fit	Notes
Dresses	Slightly Small	Consider sizing up if you’re curvier in hips or bust
Trousers & Skirts	True to Size	Waistbands tend to sit mid-rise, check hip room
Blazers & Coats	Narrow Fit	Shoulders can be snug; opt for a tailored look
Tops & Blouses	Slightly Generous	Flowy styles fit wider across bust; check fabric drape

Don’t rely on guesswork. Use Tellar.co.uk’s sizing tool to enter your measurements once and see your exact Principles size across every category.

🛍 What’s Worth Buying from Principles Right Now

1. Tailored Workwear Staples

Principles is renowned for polished officewear. Their structured blazers and tapered trousers are well cut, affordable alternatives to high-end tailoring. Just ensure the shoulder width matches your proportions.

🔎 Tip: If your hips are wider than your waist, size up in trousers and have the waist tailored for the perfect fit.

2. Versatile Day Dresses

Expect classic silhouettes with a flattering mid-length hem. Principles excels in wrap and shift dresses that transition from office to evening. Most run slightly narrow on the bust—use your Tellar profile to check this before buying.

3. Smart Casual Blouses

Perfect for layering or video calls, Principles tops often feature floaty sleeves and forgiving cuts. Best suited for those with mid-to-larger busts who want more room through the chest.

4. Seasonal Outerwear

Trench coats, wool-blend blazers, and belted coats from Principles typically run small across the shoulders. Go a size up for layering comfort, especially in winter.
