If you’ve ever tried on workout clothes and thought, “Why does everything either look boxy or ride up?”—you’re not alone. Athletic or rectangle body shapes often get left out of the fit conversation. Most activewear is either too tight in the waist (spoiler: you don’t have one) or completely shapeless.
Before we get into the good stuff, let’s make sure this is the right fit—for your actual body.
Before you grab anything new for your wardrobe, make sure you’re actually dressing for the shape you have—not the one you’re guessing at.
Start here with our Body Shape Guide — it breaks everything down in simple terms so you can shop (and dress) smarter.
What Is a Rectangle Body Shape?
Also called an athletic or straight shape, the rectangle body shape means your bust, waist, and hips are roughly the same width. You don’t have strong curves, and your waistline isn’t super defined.
You might be a rectangle shape if:
Your body feels straighter through the torso
You have longer limbs or an athletic build
Clothes often feel like they just “hang” on you
You gain weight fairly evenly—not in one specific spot
If that sounds like you? Welcome. This is where we actually talk about what works for your shape.
Still unsure?Start with our body shape guide, or save the rectangle style guide for a deeper breakdown.
Now let’s get into it: here are 10 activewear pieces for rectangle body shapes that create shape, feel comfortable, and finally make you say, “Okay, this looks good on me.”
