Understanding UK, European and US Clothing Sizes
Women’s clothing sizes don’t follow a universal standard, which is why a UK 10 isn’t the same as an EU 40 or US 6. Here’s a quick reference to help you translate between them:

How to Measure Yourself Correctly
Taking your measurements is the most reliable way to find the perfect size, especially when shopping across international size guides. All you need is a soft tape measure.
Bust
· Measure around the fullest part of your bust
· Keep the tape straight and snug but not tight
Waist
· Measure around your natural waistline, usually just above the belly button.
· Relax and breathe normally, it shouldn’t feel restrictive.
Hips
· Measure around the fullest part of your hips and bottom.
· Stand with your feet together for an accurate reading.
Inside leg (inseam)
· Measure from the top of your inner thigh to your ankle.
· Ideal for trousers, jumpsuits and longer dresses.
How to Measure Your Bra Size (The Easy Way)
Finding the right bra size can completely transform how your clothing fits. Here’s a simple step-by-step guide:
Step 1: Measure Your Band Size
1. Wrap the measure snugly around your ribcage, directly under your bust.
2. Round to the nearest whole number.
3. If the number is even, add 4. If odd, add 5. E.g. 31” -> +5 = 36
Step 2: Measure Your Bust Size
1. Measure loosely around the fullest part of your bust.
2. Round to the nearest whole number.
Step 3: Calculate Your Cup Size
Subtract your band size (step 1) from your bust measurement (step 2)

Extra Tips for Online Shopping Success
· Read product descriptions carefully: Notes like “comes up small” or “relaxed fit” are invaluable.
· Consider fabric and stretch: A fitted dress with elastane will feel roomier than a structured woven piece.
· Take new measurements every few months: Our bodies change!!
