Size Guide
Honest sizing, the same as you would get in the fitting room. If a piece runs small, we say so in the caption, every time.
What "One Size" really means
Lots of our pieces are One Size, and we know that phrase raises an eyebrow. Here is the honest version: One Size at Gigi's means a relaxed, floaty cut that is designed to fit a range of shapes rather than one exact measurement. Think wide-leg trousers with stretchy waists, swishy dresses and generous tops.
One Size does not suit every piece and every body the same way, which is why Gigi tries everything on camera and tells you how it behaves in real life: where it clings, where it floats, and whether you should think twice.
The golden rule: if you are unsure, ask. Message @gigi_my_happy_place_ with your usual dress size and Gigi will tell you honestly whether a piece will work for you. She would rather lose a sale than send you something that does not fit.
S / M / L pieces
Some fitted styles come in S, M and L. As a general guide:
| Label | Approx. UK size |
|---|---|
| S | UK 8 to 10 |
| M | UK 12 to 14 |
| L | UK 16 |
Cuts vary between pieces, so treat this as a starting point rather than a promise. Product captions will always flag anything unusual, like "drop down a size in this one".
Numbered sizes (UK 6 to 14)
A few styles, like our stretchy shorts, come in numbered UK sizes. Standard UK measurements as a general guide:
| UK size | Bust | Waist | Hips |
|---|---|---|---|
| 6 | 78 | 60 | 85 |
| 8 | 82 | 64 | 89 |
| 10 | 86 | 68 | 93 |
| 12 | 91 | 73 | 98 |
| 14 | 96 | 78 | 103 |
