NULAYER › Fit guide › Shapewear for a wrap dress
Yes, wear itA wrap dress is a V neckline by construction: one side of the bodice crosses over the other and ties at the waist. That makes it one of the easier dresses to wear a bodysuit under, because the NULAYER deep V is built to sit under low-cut dresses. The only rule is which V is on top. The bodysuit's V has to sit lower than the dress's V, or its point shows in the crossover.
Set the straps at home with the dress on. Lengthen them until the bodysuit's V is clearly below where the wrap crosses, then bend forward in the mirror, because a wrap's crossover opens when you lean. The built-in bra has no compression on the bust, so the dress drapes over your own shape; if the wrap gapes and you want more support, wear your own bra under the bodysuit with its straps under the bodysuit's straps.
A wrap's tie lands at the natural waist, which is exactly where the bodysuit's medium-firm panel does its smoothing. The tie sits over a flat panel instead of over a waistband, so there is no ridge under the knot and the dress falls from the tie in one line. That is why a wrap dress looks better over a bodysuit than over a separate brief: there is nothing at the waist for the tie to catch on.
Below the tie, a wrap skirt falls loose from the hip. That is why the mid-thigh cut works here when it would not under satin or bodycon: its leg hems sit under fabric that hangs away from the leg, so they do not print. If the wrap is a thin jersey that clings at the seat, choose the thong for the back. If the wrap is a woven fabric or has some fullness, the mid-thigh's tummy control panel under the tie is a good choice, and its extra coverage on the thigh helps when the skirt's front opening moves as you walk.
A wrap skirt opens at the front when you sit. Sit in the dress over the bodysuit at home and cross your legs. With the mid-thigh, the leg hem is what shows at the opening, in the bodysuit's shade; with the thong, it is your own leg. Choose by what you would rather see in that moment. Then stand and check the tie is still sitting over the panel, not above it. If the bodysuit has moved, the straps are too short. A wrap dress untied in a stall is a nuisance; the hook-and-eye crotch closure means you never have to untie it.
Which size: Size by bust and waist from the chart. A wrap forgives more than most dresses, so between sizes take the larger band for all-evening comfort.
| Band | US | Bust (in) | Waist (in) |
|---|---|---|---|
| XXS–XS | 0–2 | 30–33.5 | 23–26 |
| S–M | 4–10 | 34–38.5 | 26.5–31 |
| L–XL | 12–14 | 39–41 | 31.5–34.5 |
| 2XL–3XL | 16–20 | 41.5–48 | 35–41.5 |
True to size for most wearers.
Between sizes: the smaller band for maximum smoothing, the larger for all-evening comfort.
Not if the straps are set so the bodysuit's V sits lower than the dress's V. Lengthen them at home with the dress on, then lean forward in the mirror to be sure.
Both work. Thong under a clinging jersey wrap; mid-thigh under a woven or fuller wrap, where the tummy control panel sits under the tie and the leg hems are hidden by a skirt that falls loose from the hip.
Yes. The built-in bra has no compression on the bust, and your own bra goes under the bodysuit. Check in the mirror that the bra's straps and top edge sit inside the bodysuit's V, not in the crossover.
