Use this decision guide to choose the right size and support level in the Fitness Lux super stretch sport T-shirt, from cup fit to band tension.
Quick answer
Choose your usual top size in the Fitness Lux lightly padded sports top, then check two things before you commit: the removable cups sit flat against your ribcage without gaping, and the silicone underband stays put when you raise your arms. If either slips, size down rather than up.
Why the super stretch fabric changes sizing
The interlock knit in this Fitness Lux top is designed to cling, and the bonding construction removes many of the seams that normally tell you a garment is too tight. That means the fabric will not fight you at first, but it also will not hide a loose fit. A top that feels easy at the shoulders can still ride up during a workout if the band is not snug.
Treat the fit check as a two-part test: stretch first, then support. Pull the hem down over your hips and let it settle. If the band bunches or lifts away from your ribs, the size is too large for high-movement sessions, even if the bust area feels comfortable.
The trade-off: light padding versus maximum coverage
The lightly padded, removable cups are there to give shape and modesty, not to replace a high-impact sports bra. The catalog describes the top as wearable without a bra, which makes it a good match for yoga, walking, cycling, and strength training. For running or jumping, expect more bounce than a compression bra would give.
If you want a top that disappears under a shirt and still gives a smooth line, this is a sensible pick. If you need locked-in support for high-impact intervals, use it as a base layer or choose a bra with a firmer underband.
Decision rules for sizing and support
- Cup placement rule: Put the top on and press each removable cup flat against your ribcage. If the cup wrinkles or floats away at the top edge, the cup is sitting too high or the size is too large. Adjust the cup lower before changing sizes. Check cup position before you judge the band.
- Band tension rule: Raise both arms overhead and lower them slowly. The silicone underband should stay in contact with your ribs without rolling. If it slides up toward your bust, size down one step. A band that moves with your arms is too loose.
- Movement rule: Do ten jumping jacks or a short jog in place. If the top shifts enough that you need to pull it down, it is not the right size for high-movement activity. Keep it for low-impact sessions or exchange for a smaller size. Match the top to the activity, not just the mirror.
- Layering rule: If you plan to wear the top under a loose shirt, choose your usual size for a smooth line. If you want it as a standalone top with light padding only, size down for a closer fit. Decide the primary use before choosing the size.
