Both are UGG models, but lasts differ. Tasman Slipper is labeled True to Size (True to size; if between sizes or wide/thick socks, round up (not down like Classic)). Tazz is True to Size (True to size; between whole sizes often round down (lining packs out) — round up only for wide feet or thick socks).
Tasman does not follow the Classic “buy snug” rule — the braided collar is structural and will not pack out the same way. Start true to size; if between sizes, wide, or wearing thick socks, round up rather than down so heel slip stays manageable.
Does the UGG Tazz run big or small? It generally fits true to size on UGG’s scale — match your Tasman/slipper size if you already own one. Whole sizes only: between sizes, many guides prefer rounding down because the lining compresses; wide feet or thick-sock wearers may round up instead. Unlike Classic Mini/Short, do not buy intentionally snug hoping for big boot-style pack-out. Confidence is medium: TTS is consistent; between-size direction still splits.
Use the table below as a starting point from fit offsets — then confirm with try-on or returns. Width can matter more than length between these two.

| Advice | True to size; if between sizes or wide/thick socks, round up (not down like Classic) | True to size; between whole sizes often round down (lining packs out) — round up only for wide feet or thick socks |
| Width | Rigid UGGbraid collar — does not pack out like Classic boots; thick socks → round up | Platform slipper with structured upper — less pack-out than Classic Mini fleece; medium width |
| Break-in | None | Minimal; platform and upper stay relatively fixed vs Classic boots |
