The Not Your Mother's Short Jumpsuit takes a retro aerobics look and rebuilds it with a sculpting nylon-spandex blend and a built-in shelf bra for real support during training. The open back and stirrup leg keep the silhouette clean, and a seamless front avoids any digging or bunching under the compression. It moves easily from a workout to the street without losing its shape. What Our Gearhead(R) Experts Are Saying:"I've trained in this expecting it to feel like a costume, and it held compression through a full workout instead of stretching out halfway through. The support is real, not just retro styling."
