Your sizing questions answered
What if I don’t know my measurements and I don’t know my size in other brands because nothing fits?
I know it’s so hard to find clothes that actually fit your waist and get over your booty — unless it’s leggings! (Don’t worry, I’m working on more pieces soon 😉)
If you’re not sure what flower fit to pick, think about the pants you’ve tried on that fit your booty and thighs — even if the waist is too big. Then, choose the Peachay waist size that’s a full size down from that. For example, if a size 12 from another brand would usually fit your booty and thighs, go with the Daisy fit, which is roughly a size 10 waist
Our jeans are already designed with extra room for curves, so you don’t need to size up for your booty — we’ve done that for you 🍑
Still unsure? If you’re in Australia, use our Try Before You Buy option to order two sizes and try them at home. And no matter where you are, we’re always happy to help with an easy exchange if you want to swap 💕
What If I'm In-between sizes?
If you're in between sizes, here's what we recommend:
Use our Try Before You Buy option: You can order both sizes to try on at home — it’s the easiest way to find your perfect fit.
If you don't want to use the try befoer you buy option, go with the flower that aligns with your waist rather than your booty. We’ve found this works best for getting a comfy, waist-hugging fit (and don’t worry — we’ve already built in room for curves 🍑).
I’m going off the similar waist size, but I’m different sizes in different brands. What do I do?
Go with your gut size — the one you have the most of in your wardrobe that fits you well at the waist. Our jeans are designed to have extra room through the booty and thighs, so picking based on your waist is key.
If you’re in Australia, we always recommend using Try Before You Buy so you can order two sizes and only keep the one that fits best. And if it’s not quite right? You can absolutely exchange — we’ve got you 💕
Do Peachay jeans have stretch?
Yes! Our jeans have 1% elastane, which gives them the perfect amount of stretch. They’re super comfy — enough to move with you, sit down in, eat dinner in, and live your life in.
Basically: structured and stretchy. The dream combo.
Will the jeans stretch after wear?
Yes — just a little! Our denim is made with natural fibres, so it will naturally relax with wear. You can expect it to give about half a size, that's what most of our customers say.
