TLF's scrunch butt leggings — the Cosmic Seamless Scrunch Butt Leggings and the NeoCloud Secret Glute Seam Leggings — run true to size for most shoppers in 2026. The compression seam across the glute is built snug on purpose, since that's what creates the lift, and it eases within the first few wears rather than staying tight forever. If you're between two sizes or carry more through the hip and thigh, size up one; if you're going for the visible scrunch effect, order your regular size.
- TLF scrunch butt leggings run true to size for most buyers in 2026 — order your regular size in the Cosmic Seamless Scrunch Butt Leggings or NeoCloud Secret Glute Seam Leggings.
- Fit-model data on tlfapparel.com shows a 5'1", 120 lb model wearing XS and a 5'7", 128 lb model wearing S in NeoCloud Secret Glute Seam Leggings.
- Size up one if you're between sizes or want a looser waistband; the scrunch seam compresses tighter than TLF's standard leggings.
- Cosmic Seamless and NeoCloud both use glute-seam compression construction, so a snug first fit is normal and not a sign you ordered wrong.
Why this matters
Scrunch butt leggings are engineered differently than a standard legging. The seam placement across the glute compresses fabric on purpose to create the lifted, scrunched look, and that construction reads tighter on the hanger and in the first try-on than a flat-seam pair in the same size. Shoppers who don't know that end up sizing up out of caution and lose the shaping effect they bought the leggings for in the first place.
TLF publishes fit-model height, weight, and size-worn details on individual product pages, and that data is the most reliable sizing signal available since it comes straight from the brand rather than a review aggregator. Below is what that data actually says across TLF's scrunch-seam and high-waisted lines.
Do TLF scrunch butt leggings run small? Here's the fit-model data
Across the Cosmic Seamless Scrunch Butt Leggings and the NeoCloud Secret Glute Seam Leggings, TLF's own fit models land close to standard numeric sizing rather than a full size down. Here's the comparison:
| Style | Fit model | Size worn | Fit verdict |
|---|---|---|---|
| NeoCloud Secret Glute Seam Leggings | 5'1", 120 lbs | XS | True to size |
| NeoCloud Secret Glute Seam Leggings | 5'7", 128 lbs | S | True to size |
| NeoCloud Secret Glute Seam Leggings (Falcon) | 5'8", 118 lbs, 32B bust | XS | True to size |
| Tempo High Waisted Workout Leggings | 5'8", 118 lbs | XS | True to size, snug at the seam |
| Tempo High Waisted Split Hem Leggings | 5'2", 121 lbs | XS | True to size |
The pattern holds: a 5'1"-5'8" frame in the 118-128 lb range consistently lands in XS-S across TLF's glute-seam and high-waisted styles. There's no evidence in TLF's own fit data of a systematic size-down issue — the tightness shoppers feel is the compression seam doing its job, not the wrong size on the label.
Cosmic Seamless Scrunch Butt Leggings: true to size across the lineup
The Cosmic Seamless Scrunch Butt Leggings ship in Black, Falcon, Lunar Forest, and Dark Cherry, and all four colorways use the same seamless-knit construction with compression paneling at the glute. Order your usual size — sizing up loosens the seam compression that creates the scrunch effect, which defeats the point of the style.
If you carry more through the hip or thigh than your waist measurement suggests, going up one size trades some of the lift for more room through the leg. That's a fair trade for comfort during longer training sessions, but it's a deliberate choice, not a correction for a sizing flaw.
NeoCloud Secret Glute Seam Leggings: true to size, per TLF's own fit models
The NeoCloud Secret Glute Seam Leggings are the clearest sizing reference TLF publishes for this category. A 5'1", 120 lb model wears XS. A 5'7", 128 lb model wears S. A 5'8", 118 lb model with a 32B bust wears XS. That spread tracks a standard numeric chart — taller, heavier frames size up, shorter and lighter frames size down, with no evidence of a brand-wide small-fitting pattern.
Verdict: true to size. The NeoCloud fabric itself is built to feel weightless and breathable rather than rigid, so the compression at the glute seam is the main tight point, and it's confined to that panel rather than the whole leg.
Tempo High Waisted Workout Leggings: true to size with a snugger glute panel
Tempo High Waisted Workout Leggings use TLF's Luxe DNA™ fabric rather than NeoCloud, and the fit-model data shows the same true-to-size pattern: a 5'8", 118 lb model wears XS, and a 5'6", 128 lb model wears S. The high-waisted rise sits differently depending on torso length, so shoppers with a shorter torso sometimes find the waistband sits higher than expected — that's a rise difference, not a sizing error.
Verdict: true to size, with the same caveat as the scrunch-seam styles — expect a snugger first wear at the glute panel that relaxes with movement.
Why TLF legging sizing varies
- Compression level differs by seam type — scrunch-seam styles are built tighter at the glute than flat-seam leggings by design.
- Fabric family changes stretch recovery — NeoCloud and Luxe DNA™ behave differently under repeated wear, even at the same size.
- High-waisted rise fits torso length differently — a shorter torso feels a higher waistband than a longer one in the same size.
- Hip-to-waist ratio matters more than height or weight alone — two people at the same weight can size differently depending on where they carry it.
- Published fit-model data skews toward XS-S — most model specs on TLF's site cluster in the 5'1"-5'8", 118-128 lb range, so shoppers outside that range should lean on the numeric size chart rather than model comparisons alone.
Do NeoCloud leggings run small compared to Tempo leggings?
No — both lines size the same way against TLF's chart. A 5'1", 120 lb model wears XS in NeoCloud Secret Glute Seam Leggings, and a 5'8", 118 lb model wears XS in Tempo High Waisted Workout Leggings, so the two families share a consistent numeric fit rather than one running smaller than the other.
Should you size up for the scrunch butt effect?
No — sizing up loosens the compression seam and reduces the lift the scrunch construction is designed to create. Stick with your regular size unless you're between two sizes on TLF's chart, in which case sizing up trades some shaping for extra room through the hip and thigh.
What colors does the Cosmic Seamless Scrunch Butt Legging come in?
As of 2026, the Cosmic Seamless Scrunch Butt Leggings ship in Black, Falcon, Lunar Forest, and Dark Cherry. All four use the same seamless-knit build, so the sizing guidance above applies across every colorway.

If your frame falls outside it, treat the model comparisons as a directional guide and size against TLF's numeric chart first, not against a single model's stats.
