What’s My Clothes Size at PrettyLittleThing? Does PLT Run Big or Small?

PrettyLittleThing (PLT) is one of the UK’s biggest fast-fashion brands, known for ultra-trendy, curve-accentuating, party-ready fashion. Whether it’s bodycon dresses, ruched co-ords, slinky jumpsuits or contour corset tops, PLT is designed to turn heads—and hug every inch of your shape.

But with every style cut differently and sizing feedback all over the place, one question comes up again and again:
Does PLT run big or small?
And how can you confidently order the right size—especially online?

This guide breaks it down—and introduces Tellar.co.uk, the UK’s most accurate free sizing tool that gives you your precise PrettyLittleThing size in real time, based on your shape, garment type, and fabric.

Does PrettyLittleThing Run Big or Small?

PLT generally runs small, particularly in:

  • Fitted dresses (especially satin or scuba)

  • Corset tops and bodysuits

  • Non-stretch trousers and PU skirts

However:

  • Oversized hoodies, joggers, T-shirts and stretchy lounge sets are usually true to size or generous

  • Ribbed jersey and stretch co-ords can fit closely but comfortably

If you’re between sizes, curvy, or tall:

  • Size up in body-hugging and woven items

  • Stick to size or down in oversized styles

Why PLT Sizing Is Inconsistent

1. Fitted by Design

PLT’s core aesthetic leans ultra-fitted:

  • Tight sleeves

  • Snatched waists

  • Short hemlines
    It’s designed to cling and contour, so it often feels smaller than your true size—especially in woven or structured styles.

2. Fabric Variation

PLT styles range from:

  • Stretch ribbed jersey – forgiving

  • Woven satin and crepe – rigid, no stretch

  • Scuba and PU – compressive, tight fit

  • Cotton joggers and knits – soft and roomy

The same size in two different fabrics could fit completely differently.

3. Rapid Product Turnover

As a trend-led brand with daily new drops, sizing consistency varies by collection and manufacturer—which is why Tellar.co.uk helps you size each item individually and accurately.

PLT Size Chart (UK)

UK Size Bust (cm) Waist (cm) Hips (cm)
4 75 57 83
6 78 60 86
8 83 65 91
10 88 70 96
12 93 75 101
14 98 80 106
16 103 85 111
18 110 92 118
20 117 99 125

PLT also offers Petite, Tall, Plus, and Shape ranges. But the base fit block for most items is slim and short in torso length—so curvier or fuller-figured shoppers often need to adjust up.

That’s where Tellar.co.uk becomes essential.

Final Thoughts

PrettyLittleThing runs small in most fitted and structured pieces, while oversized and casualwear is more forgiving. If you’re curvy, tall, or in-between sizes, you’ll likely need to size up in dresses
